Choosing among renewed Mac Pro desktops means balancing workstation features against a platform that is now quite old. My lead pick is the 12-core Xeon model for parallel workloads, while the 64 GB quad-core configuration is the strongest fit for memory-heavy projects. The 16 GB quad-core model offers the same compact design and dual graphics at a lower starting memory level, but it calls for more restraint about workload and software compatibility.

All three are compact Late 2013-era workstations with dual FirePro D300 graphics and Thunderbolt 2, so none should be mistaken for a current-generation Mac. The meaningful differences are CPU core count, memory capacity, SSD size, and the listed operating system. I rank them by how clearly their configuration suits a particular buyer, while treating old software, limited expansion, and renewed-unit uncertainty as real tradeoffs rather than minor footnotes.

Key Takeaways
- The 12-core model is the clearest pick for multithreaded work, but its 256 GB SSD and 32 GB memory ceiling narrow its flexibility.
- The 64 GB quad-core model has the largest memory and SSD combination here, making it better suited to large projects than the other quad-core option.
- The 16 GB model shares the quad-core processor and 512 GB storage of the 64 GB pick, but its lower listed memory makes it a more limited workstation.
- Every option uses dual AMD FirePro D300 graphics and Thunderbolt 2, so buyers should check software, display, and peripheral compatibility before purchase.
- These renewed desktops are best for specific legacy, studio, or secondary-workstation needs—not buyers seeking a modern Mac platform or easy internal upgrades.

More Details on Our Top Picks
Apple Mac Pro Desktop Computer, 12-Core Intel Xeon E5 2.7 GHz, 32 GB RAM, 256 GB SSD (Renewed)
This is my first choice when the job can make use of 12 Xeon cores. Compared with both quad-core Mac Pros in this lineup, its processor gives parallel rendering, batch processing, and other well-threaded tasks more cores to work with. Its 32 GB of ECC memory also gives it a stronger workstation baseline than the 16 GB configuration, though the 64 GB model is the better option when large projects need more memory.
The trade is that this configuration pairs its core-heavy CPU with only a 256 GB PCIe SSD. That can be tight once applications, project files, and scratch space share the drive. Its stated 32 GB maximum also means there is no listed memory headroom to match the 64 GB alternative. The compact chassis and dual D300 graphics remain useful for buyers who need a small desktop with discrete graphics, but Thunderbolt 2 and the listed OS X Yosemite date this system. I would check software support and plan external storage before choosing it.
As a renewed unit, it includes a minimum 90-day warranty according to the listing, while accessories may be generic. That is less reassuring on the accessory front than the second listing, which says accessories are included. I rank this first for its distinct 12-core capability, not as the universal choice: buyers who prioritize memory capacity or onboard storage should move to the 64 GB quad-core model.
Pros:- 12-core Xeon is the lineup’s strongest option for highly parallel tasks.
- 32 GB of ECC memory exceeds the 16 GB configuration.
- Dual FirePro D300 graphics and a compact enclosure.
- Six Thunderbolt 2 ports and four USB 3.0 ports.
Cons:- 256 GB SSD leaves less room for apps and active projects than either 512 GB option.
- Listed maximum memory is 32 GB, below the 64 GB model.
- Yosemite and generic accessories call for compatibility and included-item checks.
Best for: Buyers running compatible, well-threaded production or batch workloads who want a compact Mac Pro and can work within 32 GB of memory and 256 GB of internal storage.
Not ideal for: People with large local media libraries, memory-heavy projects, modern software requirements, or a need for easy component expansion.
- Processor:12-core Intel Xeon E5 at 2.7 GHz
- Memory:32 GB 1866 MHz DDR3 ECC; listed maximum 32 GB
- Storage:256 GB PCIe flash SSD
- Graphics:Dual AMD FirePro D300, 2 GB GDDR5 VRAM each
- Operating system:Mac OS X Yosemite
- Ports:Six Thunderbolt 2; four USB 3.0
- Wireless:802.11a/b/g/n/ac Wi-Fi; Bluetooth 4.0
- Renewal and warranty:Certified refurbished; minimum 90-day warranty
Our verdict“I would choose this 12-core Mac Pro for compatible multithreaded work, provided its 256 GB drive and 32 GB memory ceiling fit the job.”
Apple Mac Pro (Late 2013), 3.7 GHz Quad-Core Xeon, 64 GB RAM, 512 GB SSD (Renewed)
The most capable configuration for buyers who need room for larger working sets is this 64 GB quad-core Mac Pro. Its processor has fewer cores than the 12-core model, so it is not my pick for workloads that scale well across many cores. But it doubles that model’s listed memory capacity and combines it with a 512 GB SSD, giving applications and project files more breathing room than the 16 GB or 256 GB alternatives.
That combination suits tasks where memory capacity matters more than core count, such as keeping sizable creative projects or multiple demanding applications open, assuming the software remains compatible. It retains dual FirePro D300 graphics and the shared set of six Thunderbolt 2 ports and four USB 3.0 ports. Compared with the 16 GB quad-core option, this listing makes a stronger workstation case through its memory configuration; compared with the 12-core unit, it gives up CPU cores for a larger memory pool and storage drive.
The weaknesses are platform-wide, not hidden: this is a Late 2013 design with limited internal expansion and older connectivity. Its listing specifies macOS Sierra, which is still an old operating system for a desktop intended for current general use. The generic box also does not promise retail-style packaging, and I would confirm which accessories arrive even though the listing says they are included. I place it second because its useful memory and storage advantage is specific and substantial, but the quad-core CPU and aging software keep it from being the default pick.
Pros:- 64 GB of ECC memory is the largest capacity in this comparison.
- 512 GB SSD provides twice the internal capacity of the 12-core option.
- Dual FirePro D300 graphics and broad legacy connectivity.
- Listing states that accessories are included and gives a minimum 90-day warranty.
Cons:- Quad-core CPU has fewer cores than the 12-core model.
- Limited internal expansion restricts later hardware changes.
- macOS Sierra and generic packaging require realistic expectations.
Best for: Buyers with compatible workflows that benefit from 64 GB of memory and 512 GB of internal storage more than they benefit from a higher CPU core count.
Not ideal for: People whose software depends on many CPU cores, buyers requiring current macOS support, or anyone who expects easy internal expansion.
- Model:Late 2013 Mac Pro ME253LL/A
- Processor:3.7 GHz quad-core Intel Xeon E5-1620 v2
- Memory:64 GB 1866 MHz DDR3 ECC SDRAM
- Storage:512 GB SSD
- Graphics:Dual AMD FirePro D300, 2 GB GDDR5 each
- Ports:Six Thunderbolt 2, four USB 3.0, one HDMI 1.4
- Networking:Dual Gigabit Ethernet, 802.11ac Wi-Fi, Bluetooth 4.0
- Operating system:macOS Sierra
- Condition and warranty:Certified refurbished; minimum 90-day warranty
Our verdict“I would pick this version when memory and a larger SSD matter more than the 12-core model’s parallel-processing advantage.”
Apple Mac Pro Desktop Computer, 3.7 GHz Quad-Core Intel Xeon E5, 16 GB RAM, 512 GB SSD (Renewed)
This is the simplest entry point into the lineup’s compact 2013 Mac Pro design, with a 3.7 GHz quad-core Xeon, dual D300 graphics, and a 512 GB PCIe flash SSD. That drive is twice the stated capacity of the 12-core model, which can make everyday file handling less cramped. Against the 64 GB quad-core configuration, however, it has the same broad processor class and storage capacity but only 16 GB of ECC memory. That is the clearest reason to choose it only for modest, defined workloads rather than treating it as an equal alternative.
Its six Thunderbolt 2 ports and four USB 3.0 ports support a range of older peripherals and external storage, while the compact enclosure is easier to place than a traditional tower. The dual FirePro cards provide discrete graphics hardware, but their presence does not make this an up-to-date graphics workstation. The supplied OS X Yosemite listing is especially limiting for buyers who need recent applications, security updates, or current platform support. I would confirm the seller’s exact installed system and the app versions that can run before purchase.
Where the 64 GB configuration is the more convincing workstation for memory-intensive projects, this 16 GB version makes more sense as a secondary Mac for compatible legacy software, light production, or a carefully scoped setup. The listing says memory is 16 GB maximum, so it offers no stated capacity path toward the 64 GB unit’s headroom. I rank it third because its core platform and SSD remain useful in narrow cases, but the memory ceiling and old OS reduce its range.
Pros:- 512 GB PCIe flash storage exceeds the 12-core model’s drive capacity.
- Compact Mac Pro enclosure with dual dedicated graphics.
- Six Thunderbolt 2 ports and four USB 3.0 ports.
- ECC memory is specified for the workstation platform.
Cons:- 16 GB listed memory maximum is far below the 64 GB alternative.
- OS X Yosemite may not support the software or security needs of a current desktop.
- Quad-core processor lacks the 12-core model’s parallel-work advantage.
Best for: Buyers seeking a compact renewed Mac for light, compatible legacy applications or a secondary workstation with a 512 GB SSD.
Not ideal for: People running memory-heavy creative work, expecting to upgrade beyond the listed 16 GB maximum, or needing modern macOS and app support.
- Model:ME253LL/A
- Processor:3.7 GHz quad-core Intel Xeon E5
- Memory:16 GB 1866 MHz DDR3 ECC; listed maximum 16 GB
- Storage:512 GB PCIe flash SSD
- Graphics:Dual AMD FirePro D300, 2 GB GDDR5 VRAM each
- Operating system:OS X Yosemite
- Ports:Six Thunderbolt 2; four USB 3.0
- Wireless:802.11ac Wi-Fi; Bluetooth 4.0
- Condition:Renewed
Our verdict“I would choose this Mac Pro only for a modest, compatible workload where its 512 GB SSD matters more than memory headroom.”
How We Picked
I compared these three listings by the practical differences that can change a workstation purchase: processor capacity, memory, storage, graphics, connectivity, and renewal details. The 12-core system earns the performance-focused position because its additional cores are a meaningful distinction for software that can spread work across them. I did not treat core count as an automatic win for every buyer: the quad-core systems have faster listed per-core clock rates and more SSD capacity, and the 64 GB configuration is the only one with that larger memory pool.
I also weighed the age of the platform. Each desktop is based on the compact 2013 Mac Pro design, with dual D300 graphics and Thunderbolt 2, and the supplied system software listings are old. The listing descriptions identify renewed or certified refurbished condition, but they do not establish identical refurbishment processes or accessories. I therefore rank these by their stated configurations and likely buyer fit, not by assumptions about cosmetic condition, actual battery-free desktop longevity, or performance beyond the supplied specifications.
Finally, I gave real weight to the limits: internal expansion is constrained, storage can fill quickly, and older operating systems may block current apps or security expectations. A product can be a reasonable renewed workstation for a compatible, defined task without being a sensible general-purpose Mac for everyone. Before buying, I would verify the exact unit, installed operating system, return terms, warranty coverage, and included accessories with the seller.

Factors to Consider When Choosing Renewed Mac Pro Desktops
Before choosing among these renewed Mac Pros, I would match the configuration to a specific workload and check whether the machine’s age fits my software and support needs. Their similar chassis and graphics can make the listings seem interchangeable; CPU cores, memory, internal storage, and system software tell a more useful story.
Choose CPU cores for the work you actually run
The 12-core model stands apart when software can divide a task across many cores. Rendering, encoding, and batch work may benefit more from that configuration than from the quad-core options. The two quad-core listings instead offer a 3.7 GHz processor and should not be dismissed solely because they have fewer cores: a workflow that is lightly threaded may not use twelve cores effectively. I would check the requirements and real behavior of the exact applications before making core count the deciding factor.
If the workload is mixed or unclear, the extra cores are not a guarantee of a better experience across every task. The 12-core version also has the smallest SSD and a lower stated memory ceiling than the 64 GB model. Think of it as a focused choice for parallel processing, not an across-the-board upgrade.
Treat memory and storage as separate limits
The 64 GB configuration is the clear choice when large projects, virtual machines, or several demanding applications need memory at once. The 32 GB model occupies the middle ground, while the 16 GB model is best kept to lighter or tightly scoped tasks. These listings state different maximum memory capacities, so do not assume they can all be upgraded to the same amount.
Storage tells a separate story: both quad-core options list 512 GB, while the 12-core system has 256 GB. A smaller SSD can be managed with external storage, but external drives add cost, desk clutter, and another compatibility question. Check the ports and drive needs of your setup before counting on that workaround.
Check software age before buying the hardware
The listings identify operating systems ranging from OS X Yosemite to macOS Sierra, which are old releases. That matters because newer applications, security expectations, and peripheral drivers may not align with those systems. I would verify the specific apps and versions required, along with the seller’s details on the installed system and any available upgrade path. Do not buy on the assumption that an older Intel Mac can run every current macOS release.
Also confirm whether the software you rely on needs a particular graphics feature or newer processor support. The dual FirePro D300 cards are a shared feature across these picks, not a guarantee of compatibility with modern production tools.
Plan around Thunderbolt 2 and limited expansion
Six Thunderbolt 2 ports and four USB 3.0 ports give these desktops useful connections for older displays, storage, and peripherals. Still, Thunderbolt 2 is not Thunderbolt 3 or 4, and a newer device may need an adapter or may not work as expected. Check cable, display, and accessory requirements in advance, especially if the Mac will anchor a studio desk.
The compact cylindrical design also limits internal expansion compared with a conventional tower. If you expect to add drives, modern graphics hardware, or other internal components later, these are poor fits. I would choose one only when its fixed configuration already covers the intended setup.
Verify renewed-unit terms and included items
Renewed condition does not mean every listing has identical inspection standards, cosmetic condition, or accessories. One listing states a minimum 90-day warranty and notes that accessories may be generic; another says accessories are included and also lists a minimum 90-day warranty. Those statements are not a substitute for checking the seller’s current return policy, warranty scope, and exact box contents.
Before placing an order, I would confirm the model identifier, memory and SSD configuration, power cable and other included accessories, and whether the unit has been tested. Ask what support applies if the desktop arrives with a fault or a specification that differs from the listing. That matters particularly with an older workstation whose parts and software can be harder to replace or support.
Frequently Asked Questions
Which renewed Mac Pro in this comparison is best for multithreaded work?
The 12-core 2.7 GHz Xeon model is the strongest match when a compatible application can use many CPU cores. It has substantially more cores than either quad-core option, though it also has less storage than both and a stated 32 GB memory ceiling. For workloads that need a large memory pool more than extra cores, the 64 GB quad-core model may be a better fit.
Is the 64 GB quad-core model a better choice than the 12-core model?
It depends on the workload. The 64 GB version is preferable when memory capacity and its 512 GB SSD matter most, while the 12-core option is a more targeted pick for parallel processing. Neither has an across-the-board advantage: compare your applications’ CPU scaling and memory needs, then account for the older operating system and limited expansion shared by this generation.
Can I use these renewed Mac Pros for current software?
Do not assume that you can. The supplied listings name OS X Yosemite or macOS Sierra, both older systems, and application support varies by software and version. Before buying, check the exact program requirements, available operating-system support for the specific Mac, and whether required security updates or peripheral drivers are available. A renewed label does not make the hardware a current-generation Mac.
Which option has the most room for files and projects?
The two quad-core listings each specify a 512 GB SSD, while the 12-core model lists a 256 GB PCIe SSD. That makes either quad-core configuration less cramped for internal files, although actual usable capacity will be lower after the operating system and applications are installed. External storage may help, but check whether its connection and speed meet your workflow.
What should I verify before ordering a renewed Mac Pro?
I would confirm the precise model and configuration, the installed operating system, condition description, warranty coverage, return terms, and all included accessories. Check that the listed memory and SSD match the unit being sold, and ask about testing or refurbishment details if they are unclear. Also verify compatibility with your software, displays, and Thunderbolt 2 or USB accessories before relying on the desktop for daily work.
Conclusion
For buyers whose software benefits from many CPU cores, I would start with the 12-core Mac Pro, accepting its 256 GB SSD and 32 GB memory limit. If a project needs more working memory and storage, the 64 GB quad-core model is the better match, as long as four cores suit the workload. The 16 GB quad-core configuration makes the most sense as a secondary desktop or for modest legacy tasks, not as the most flexible workstation here.
All three picks belong to an older platform with limited expansion, aging operating systems, and Thunderbolt 2 connectivity. I would buy only after checking current seller terms and confirming software compatibility. If your priority is modern macOS support, current peripheral standards, or a clear upgrade path, I would skip these renewed Mac Pros and compare newer Macs instead.
