AMD FirePro D700 vs AMD Radeon RX 6750 XT Comparison

AMD Radeon RX 6750 XT vs AMD FirePro D700

The benchmark data presents a stark generational clash: the AMD Radeon RX 6750 XT and the AMD FirePro D700 are nearly inseparable in aggregate performance, yet they achieve parity through entirely different strengths. The RX 6750 XT dominates modern graphics APIs with a 250.7% lead in Vulkan, while the FirePro D700 counters with a 31% advantage in OpenCL compute. This is not a simple "newer is better" story; it is a tale of two architectures optimized for different workloads, with the final choice hinging on whether the user prioritizes contemporary gaming and rendering or legacy compute tasks.

Head-to-Head Benchmarks

The only direct benchmark comparison available is the head-to-head data, which reveals a complete split in victories. In the Geekbench Vulkan test, the AMD Radeon RX 6750 XT delivers a score of 98089, dwarfing the FirePro D700's 27968. This translates to a massive delta of 250.7%, indicating that the RX 6750 XT is over three and a half times faster in this API. This is a decisive win for the modern card, showcasing its ability to leverage the low-level, high-efficiency Vulkan interface to extract far more performance from its hardware.

Conversely, the AMD FirePro D700 wins the Geekbench OpenCL test with a score of 23716, compared to the RX 6750 XT's 16360. The delta is -31%, meaning the FirePro D700 is 31% ahead. This is a significant margin in a compute-heavy benchmark, suggesting that the older GCN architecture has a specific advantage in raw, general-purpose compute tasks that are not tied to modern graphics pipelines. The win is not a fluke; it is a consistent pattern of the FirePro D700 outperforming in OpenCL, a workload where its design excels.

These two results explain why the average benchmark scores are so close. The RX 6750 XT's average score is 26011, while the FirePro D700's is 25842, a difference of only 0.7%. The massive Vulkan win for the RX 6750 XT is nearly perfectly offset by the FirePro D700's OpenCL advantage. The data shows a tie in wins, with each card taking one benchmark, but the nature of the victories is telling. The RX 6750 XT's win is a landslide in a modern API, while the FirePro D700's win is a solid, but less dramatic, lead in a compute standard.

Where Each One Wins

The use-case split is defined by the benchmarks. The AMD Radeon RX 6750 XT is the clear winner for any workload that utilizes the Vulkan API. This includes modern games and applications that have moved to this low-overhead graphics standard. Its 250.7% lead in this area is not a marginal improvement; it is a categorical superiority that makes the FirePro D700 non-competitive for Vulkan-based tasks. For users building a system for contemporary gaming or using software with Vulkan renderers, the RX 6750 XT is the only logical choice based on this data.

The AMD FirePro D700, despite its age, wins in OpenCL compute. Its 31% lead over the RX 6750 XT in Geekbench OpenCL suggests that for certain types of computational workloads, such as scientific simulation, data analysis, or other GPGPU tasks that rely heavily on OpenCL, it holds a distinct edge. This is a classic strength of the GCN architecture, which was designed with compute in mind. The FirePro D700's advantage here is substantial and indicates that it can still serve a purpose in systems where OpenCL performance is the primary metric, even if its other capabilities are dated.

The broader benchmark suite reinforces the RX 6750 XT's overall versatility. It posts scores of 20700 in Passmark G3D and 9550 in Passmark GPU Compute, alongside a Geekbench Metal score of 137249. These results, while not directly comparable to the FirePro D700 due to missing data, show a well-rounded card that handles both graphics and compute with high proficiency. The FirePro D700, with only two recorded benchmarks, appears more specialized, excelling in its niche but lacking the breadth of performance that the RX 6750 XT demonstrates across the board.

Architecture Differences

The architectural gap between these two GPUs is vast, representing a decade of evolution. The AMD Radeon RX 6750 XT is built on the RDNA 2.0 architecture using the Navi 22 chip, while the AMD FirePro D700 uses the older GCN 1.0 architecture with the Tahiti chip. This is a fundamental difference in design philosophy. RDNA 2.0 is optimized for high clock speeds and efficient gaming performance, whereas GCN 1.0 was designed for compute throughput and was the foundation for AMD's earlier data center and workstation efforts.

The manufacturing process highlights the generational leap. The RX 6750 XT is fabricated on a 7 nm process at TSMC, while the FirePro D700 uses a 28 nm process. This allows the RX 6750 XT to pack 17,200 million transistors into a 335 mm² die, resulting in a transistor density of 51.3M per mm². In contrast, the FirePro D700 has only 4,313 million transistors on a slightly larger 352 mm² die, yielding a density of just 12.3M per mm². The 7 nm process is the primary enabler of the RX 6750 XT's higher clock speeds and efficiency.

The feature sets are also from different eras. The RX 6750 XT includes 40 dedicated ray tracing cores, a feature entirely absent from the FirePro D700. It also supports DirectX 12 Ultimate (12_2), while the FirePro D700 is limited to DirectX 12 (11_1). The RX 6750 XT supports Vulkan 1.4, whereas the FirePro D700 supports Vulkan 1.2.170. These API and feature differences directly explain the RX 6750 XT's dominance in modern workloads, as it has the hardware and software support to handle modern rendering techniques that the older card cannot.

Specification Differences

The most striking specification difference is in memory. The RX 6750 XT comes with 12 GB of GDDR6 memory on a 192-bit bus, delivering a bandwidth of 432.0 GB/s. The FirePro D700 has 6 GB of GDDR5 memory on a wider 384-bit bus, but its bandwidth is only 263.0 GB/s. The RX 6750 XT has double the capacity and 64% more bandwidth, a critical advantage for high-resolution textures and large datasets.

Compute and rendering capabilities also differ significantly. The RX 6750 XT has 2560 shading units, 160 texture mapping units, and 64 ROPs, compared to the FirePro D700's 2048 shading units, 128 TMUs, and 32 ROPs. This translates to a pixel rate of 166.4 GPixel/s and a texture rate of 416.0 GTexel/s for the RX 6750 XT, versus 27.20 GPixel/s and 108.8 GTexel/s for the FirePro D700. The FP32 performance is 13.31 TFLOPS for the RX 6750 XT, nearly four times the FirePro D700's 3.482 TFLOPS. The RX 6750 XT also offers FP16 performance at 26.62 TFLOPS, a feature the FirePro D700 lacks entirely.

Other differences include clock speeds and connectivity. The RX 6750 XT has a base clock of 2150 MHz and a boost clock of 2600 MHz, while the FirePro D700's clocks are not specified. The RX 6750 XT uses a PCIe 4.0 x16 interface, while the FirePro D700 uses PCIe 3.0 x16. The display outputs also differ: the RX 6750 XT has 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the FirePro D700 has 6x mini-DisplayPort 1.2 and 1x SDI, reflecting its workstation heritage. The RX 6750 XT also has a specified power draw of 250 W and requires a 600 W PSU, while the FirePro D700 has a higher TDP of 274 W but the same suggested PSU.

The Verdict

The data makes the choice clear for most users: the AMD Radeon RX 6750 XT is the superior product. Its 250.7% lead in Vulkan is decisive, and its architectural advantages—including ray tracing support, a 7 nm process, double the memory, and nearly four times the FP32 performance—make it the more capable and future-proof option. It also matches the FirePro D700 in average score, proving it is not sacrificing overall performance for its modern features.

The AMD FirePro D700 is only the right choice for a very specific niche. If a user's primary workload is OpenCL compute, and the 31% lead in that benchmark is the single most important metric, then the FirePro D700 holds an advantage. However, this is a narrow use case. The card's lack of modern API support, limited memory, and significantly lower raw compute power outside of OpenCL make it a difficult recommendation. The data suggests that for nearly all applications, the RX 6750 XT is the better investment, offering a balance of modern features and competitive overall performance that the older FirePro D700 simply cannot match.
