GPU Comparison

The AMD Radeon PRO W7700 holds a decisive lead over the NVIDIA Quadro GP100 in the available benchmark data, winning the sole head-to-head test by a significant margin. In Geekbench OpenCL, the W7700 scores 108,245 against the GP100’s 87,445, a 23.8% advantage that places the AMD card in a different performance tier. The W7700’s average benchmark score of 118,976 also dwarfs the GP100’s 87,445, and its 95th percentile ranking among all GPUs versus the GP100’s 93rd underscores the generational gap between these two workstation cards.

Head-to-Head Benchmarks

The only direct comparison available is Geekbench OpenCL, and it is not close. The AMD Radeon PRO W7700 delivers 108,245 points, while the NVIDIA Quadro GP100 manages 87,445 points. That works out to a 23.8% delta in favor of the W7700, a massive gap that reflects the fundamental architectural advantages of the newer card.

This performance disparity is consistent with the broader benchmark averages. The W7700’s average score across its two recorded tests (OpenCL and Vulkan) is 118,976, whereas the GP100’s single OpenCL result gives it an average of 87,445. The W7700 also outperforms several close rivals in its own tier, it sits just 1.3% above the NVIDIA GB10 and 1.6% above the RTX 4000 SFF Ada Generation, while leading the Tesla V100 SXM2 by 4% and the RTX A5500 Mobile by 4.4%.

The GP100, by contrast, is clustered with much weaker hardware. Its 87,445 average is only 0.4% better than the AMD Radeon PRO W7600, and it sits 2.1% above the NVIDIA CMP 40HX. Crucially, the GP100 actually loses to both the RTX A4500 Mobile and the desktop RTX A4500, trailing them by 4% and 4.6% respectively. This means the GP100 is not merely outclassed by the W7700, it is also inferior to several modern mid-range workstation cards that the W7700 itself beats comfortably.

In Vulkan, the W7700 posts an even higher score of 129,706, though no comparable Vulkan result exists for the GP100. This suggests the AMD card scales better across different graphics APIs, a point reinforced by its support for Vulkan 1.4 versus the GP100’s Vulkan 1.3.

Architecture Differences

The two cards represent radically different eras of GPU design. The AMD Radeon PRO W7700 uses the Navi 32 chip built on RDNA 3.0 architecture, fabricated on TSMC’s 5 nm process node. It packs 28,100 million transistors into a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The NVIDIA Quadro GP100, by contrast, uses the GP100 chip on the older Pascal architecture, built on a 16 nm process. It contains 15,300 million transistors spread across a much larger 610 mm² die, giving it a density of just 25.1 million per square millimeter.

These architectural differences translate into stark clock speed advantages for AMD. The W7700 runs at a base clock of 1900 MHz and boosts to 2600 MHz, while the GP100 is limited to 1304 MHz base and 1443 MHz boost. The AMD card’s memory clock is also far higher at 2250 MHz (18 Gbps effective) compared to the GP100’s 715 MHz (1430 Mbps effective).

Memory configurations tell a more nuanced story. Both cards have 16 GB of VRAM, but the type and bus width differ drastically. The W7700 uses GDDR6 on a 256-bit bus, delivering 576.0 GB/s of bandwidth. The GP100 uses HBM2 on a massive 4096-bit bus, which gives it superior bandwidth of 732.2 GB/s, a 27% advantage over the W7700. This is the one specification where the older card wins, and it reflects the GP100’s HPC-oriented design heritage.

Shader resources also favor AMD heavily. The W7700 has 3072 shading units, 192 texture mapping units, and 96 ROPs, while the GP100 has 3584 shading units, 224 TMUs, and 96 ROPs. NVIDIA’s card technically has more raw shader cores, but AMD’s higher clocks and newer architecture more than compensate. The W7700 also includes 48 dedicated ray tracing cores, a feature entirely absent from the Pascal-based GP100.

Compute throughput is where the generation gap becomes most apparent. The W7700 delivers 31.95 TFLOPS of FP32 performance and 63.90 TFLOPS of FP16 (2:1 ratio), while the GP100 manages just 10.34 TFLOPS FP32 and 20.69 TFLOPS FP16. AMD’s card is roughly 3x faster in both precision formats. Pixel fill rates follow the same pattern: 249.6 GPixel/s for the W7700 versus 138.5 GPixel/s for the GP100, and texture rates of 499.2 GTexel/s versus 323.2 GTexel/s.

Connectivity and features also diverge. The W7700 uses PCIe 4.0 x16, while the GP100 is limited to PCIe 3.0 x16. Display outputs differ too: the W7700 offers four DisplayPort 2.1 connections, while the GP100 has one DVI and four DisplayPort 1.4a outputs. API support favors AMD as well, with DirectX 12 Ultimate (12_2) versus the GP100’s DirectX 12 (12_1), and Vulkan 1.4 versus 1.3. Both cards support OpenGL 4.6.

Power requirements follow the performance gap. The W7700 has a 190 W TDP and requires a 450 W PSU, while the GP100 draws 235 W and needs a 550 W PSU. Both are dual-slot cards with a single 8-pin power connector, but the GP100 is longer at 267 mm versus the W7700’s 241 mm.

The Verdict

The data paints an unambiguous picture: the AMD Radeon PRO W7700 is the superior workstation GPU by a wide margin. Its 23.8% lead in OpenCL performance, combined with its 95th percentile ranking versus the GP100’s 93rd, makes it the clear choice for any modern workload.

The W7700’s advantages are not incremental, they are transformative. It is roughly 3x faster in raw FP32 and FP16 compute, has ray tracing capabilities the GP100 lacks entirely, supports newer PCIe and DisplayPort standards, and consumes 45 W less power while delivering dramatically higher performance. The newer 5 nm process and RDNA 3.0 architecture give it a decisive edge in efficiency and feature support.

The GP100’s only clear win is memory bandwidth, where its HBM2 configuration provides 732.2 GB/s versus the W7700’s 576.0 GB/s. This could matter for bandwidth-bound HPC workloads, but the W7700’s massive compute advantage likely overcomes this in most real-world scenarios.

For anyone choosing between these two cards today, the W7700 is the rational pick. It offers modern features, superior performance, better API support, and lower power draw. The GP100 is an end-of-life product (production status: End-of-life) from 2016, while the W7700 launched in November 2023. The only reason to select the GP100 would be if a specific workload absolutely requires its unique HBM2 memory bandwidth characteristics.

Where Each One Wins

AMD Radeon PRO W7700, Compute and Modern Workloads

The W7700 is the definitive winner in raw compute performance. Its 31.95 TFLOPS FP32 and 63.90 TFLOPS FP16 throughput are roughly 3x the GP100’s 10.34 and 20.69 TFLOPS respectively. This makes it ideal for GPU-accelerated rendering, simulation, and machine learning inference. The inclusion of 48 ray tracing cores gives it a massive advantage in ray-traced visualization work, a feature the GP100 lacks entirely. Its newer PCIe 4.0 interface and DisplayPort 2.1 outputs also make it better suited for modern workstation builds and high-resolution displays.

NVIDIA Quadro GP100, Bandwidth-Constrained HPC

The GP100’s only meaningful advantage is its 732.2 GB/s memory bandwidth, which exceeds the W7700’s 576.0 GB/s by 27%. For workloads that are purely memory-bandwidth-bound, such as certain large-scale scientific simulations or database processing, this could provide a tangible benefit. The GP100’s larger 610 mm² die and 4096-bit bus reflect its HPC-oriented design, even if its older Pascal architecture limits its overall compute capabilities. However, this singular advantage is unlikely to compensate for the W7700’s superior performance in most scenarios, especially given the GP100’s end-of-life status.
