AMD Radeon PRO W7800 vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark scores for the AMD Radeon PRO W7800, while the NVIDIA B200 SXM6 has no benchmark entries. This asymmetry shapes the entire comparison. The Radeon PRO W7800 delivers a Geekbench OpenCL score of 154366 and a Geekbench Vulkan score of 175422, producing an average benchmark score of 164894. The B200 SXM6, by contrast, holds an average benchmark score of 0 and sits in the 50th percentile among all GPUs, a placeholder position that reflects the absence of measured results rather than actual performance.

The Radeon PRO W7800 ranks in the 97th percentile against all GPUs, placing it near the top of the database. Its nearest rivals, all NVIDIA workstation cards, show how tightly contested this segment is. The RTX A5500 averages 165217, just 0.2 percent ahead of the Radeon. The RTX 4500 Ada Generation averages 166094, a 0.7 percent lead. The AMD Radeon Pro W6900X averages 168574, 2.2 percent ahead. Only the A100 PCIe 40 GB trails the Radeon, with an average of 162504, which puts the Radeon 1.5 percent ahead. These delta values indicate that the Radeon PRO W7800 sits in a competitive cluster where single percentage points separate adjacent products.

Without any B200 SXM6 benchmark data, a direct head-to-head score comparison is impossible. The database records zero wins for either product in head-to-head tests. The B200 SXM6 has no nearest rivals listed, no average score, and no percentile data beyond the neutral 50th percentile default. This means the analysis must proceed on architectural specifications and the single measured product, the Radeon PRO W7800, while acknowledging the B200 SXM6 as an unmeasured entry.

The Verdict

The data shows two products with entirely different roles. The AMD Radeon PRO W7800 has verified benchmark scores, a 97th percentile ranking, and a measurable position among workstation rivals. The NVIDIA B200 SXM6 has no benchmarks, no rivals, and no performance data in the database. Any user selecting between them must rely on the recorded specifications, because the database offers no comparative performance results.

The Radeon PRO W7800 delivers 45.25 TFLOPS of FP32 compute and 90.50 TFLOPS of FP16 compute with a 2:1 ratio, making it a capable workstation card for graphics and compute workloads. Its 32 GB of GDDR6 memory on a 256 bit bus provides 576.0 GB/s of bandwidth. The B200 SXM6 offers 69.34 TFLOPS of FP32 and 69.34 TFLOPS of FP16 with a 1:1 ratio, meaning its FP16 throughput equals rather than doubles its FP32 rate. Its 180 GB of HBM3e memory on an 8192 bit bus delivers 8.19 TB/s of bandwidth, a massive margin over the Radeon.

The B200 SXM6 is a server module with no display outputs and no graphics API support, while the Radeon PRO W7800 is a dual-slot workstation card with DisplayPort outputs and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. The verdict from the data: the Radeon PRO W7800 is the only choice for graphics and display workloads, while the B200 SXM6 targets memory-bound server compute where its 8.19 TB/s bandwidth and 180 GB capacity dominate. The B200 SXM6 also lists no tensor core count for the Radeon, but the B200 SXM6 includes 592 tensor cores, a feature the Radeon lacks entirely.

Architecture Differences

The two GPUs come from different architecture families and different design philosophies. The AMD Radeon PRO W7800 uses the Navi 31 chip with RDNA 3.0 architecture, codenamed Plum Bonito, and belongs to the Radeon Pro Navi (Navi III Series) generation. The NVIDIA B200 SXM6 uses the GB100 chip with Blackwell architecture and belongs to the Server Blackwell (Bxx) generation. Both are fabricated by TSMC on a 5 nm process, but the similarities end there.

The transistor counts differ dramatically. The Radeon PRO W7800 packs 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per mm². The B200 SXM6 integrates 208,000 million transistors on a 1628 mm² die, a density of 127.8 million per mm². The B200 SXM6 die is nearly three times larger and carries over three and a half times the transistor count. This scale difference reflects the server-oriented design of the B200 SXM6 versus the workstation focus of the Radeon.

The compute configurations diverge sharply. The Radeon PRO W7800 has 4480 shading units, 280 texture mapping units, 128 render output units, and 70 ray tracing cores. It has no tensor cores. The B200 SXM6 has 18944 shading units, 592 texture mapping units, and only 24 render output units. It has 592 tensor cores and no listed ray tracing cores. The B200 SXM6's low ROP count of 24, paired with a pixel rate of 43.92 GPixel/s, indicates it is not designed for rasterization. The Radeon PRO W7800 achieves 323.2 GPixel/s, over seven times the pixel throughput.

Memory architecture separates the two further. The Radeon uses 32 GB of GDDR6 across a 256 bit bus. The B200 SXM6 uses 180 GB of HBM3e across an 8192 bit bus. The B200 SXM6 memory bandwidth of 8.19 TB/s is over 14 times the Radeon's 576.0 GB/s. Clock speeds also differ: the Radeon bases at 1895 MHz and boosts to 2525 MHz, while the B200 SXM6 bases at 120 MHz and boosts to 1830 MHz. The Radeon's memory runs at 2250 MHz (18 Gbps effective), while the B200 SXM6 memory runs at 2000 MHz (8 Gbps effective).

The B200 SXM6 supports PCIe 6.0 x16, while the Radeon PRO W7800 uses PCIe 4.0 x16. Power requirements reflect the B200 SXM6's server role: its TDP is 1000 W with a suggested PSU of 1400 W, while the Radeon draws 260 W with a suggested PSU of 600 W. The B200 SXM6 is an SXM module with no dimensions recorded, no display outputs, and no graphics API support. The Radeon is a dual-slot card measuring 280 mm by 110 mm by 40 mm, with 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1 outputs.

Where Each One Wins

The AMD Radeon PRO W7800 wins in every graphics-oriented category recorded. Its 323.2 GPixel/s pixel rate and 707.0 GTexel/s texture rate far exceed the B200 SXM6's 43.92 GPixel/s and 1,083.4 GTexel/s. The Radeon's shading unit count of 4480, while lower than the B200's 18944, pairs with 128 ROPs to produce rasterization throughput suited to workstation display workloads. The Radeon's 70 ray tracing cores provide hardware acceleration for ray-traced rendering, a feature the B200 SXM6 lacks entirely. The Radeon also supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it compatible with standard graphics APIs.

The Radeon PRO W7800 also wins on power efficiency per the recorded specifications. Its 260 W TDP and 600 W suggested PSU contrast with the B200 SXM6's 1000 W TDP and 1400 W suggested PSU. The Radeon's dual-slot form factor and 280 mm length allow installation in standard workstation chassis, while the B200 SXM6 requires an SXM module slot, typically found only in dense server platforms. The Radeon's 2x 8-pin power connectors are standard for workstation power supplies, whereas the B200 SXM6 lists no power connectors, indicating a proprietary server power delivery system.

The NVIDIA B200 SXM6 wins decisively in memory capacity, bandwidth, and raw compute throughput. Its 180 GB of HBM3e memory dwarfs the Radeon's 32 GB, and its 8.19 TB/s bandwidth enables data movement at a scale the Radeon cannot approach. The B200 SXM6's FP32 throughput of 69.34 TFLOPS exceeds the Radeon's 45.25 TFLOPS, and its FP16 throughput of 69.34 TFLOPS, while lower than the Radeon's 90.50 TFLOPS at 2:1 ratio, comes at a 1:1 ratio that may indicate different precision handling. The B200 SXM6's 592 tensor cores provide dedicated matrix math acceleration, valuable for AI inference and training workloads. Its PCIe 6.0 x16 interface doubles the bandwidth potential of the Radeon's PCIe 4.0 x16.

The B200 SXM6 also wins on transistor count and die size, with 208,000 million transistors on 1628 mm² versus 57,700 million on 529 mm². This scale enables the B200 SXM6's massive memory interface and compute resources. The B200 SXM6's release date of 2024-10-31 places it after the Radeon's 2023-04-12 release, and its successor, Server Rubin, indicates an active product roadmap. The Radeon's predecessor is Radeon Pro Vega, and it has no successor listed.
