AMD Radeon RX 7700 XT vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the AMD Radeon RX 7700 XT and the NVIDIA B200 SXM6. The head-to-head benchmark array is empty, and the win counts for both parts stand at zero. This absence of comparative measurements reflects the fundamentally different positioning of these two products in the market.

The AMD Radeon RX 7700 XT carries a full set of consumer-oriented benchmark data. Its average benchmark score across the recorded tests is 22,549. The GPU sits at the 67th percentile among all GPUs in the database. Its nearest rival, the NVIDIA GeForce RTX 5060 Mobile, scores 22,435, a delta of 0.5 percent in favor of the Radeon.

Architecture Differences

The AMD Radeon RX 7700 XT uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename Wheat Nas. It belongs to the Navi III (RX 7000) generation. The NVIDIA B200 SXM6 uses the GB100 chip built on Blackwell architecture, with the generation designation Server Blackwell (Bxx). Both parts are fabricated on a 5 nm process at TSMC, but the similarities end there.

Transistor counts differ enormously. The RX 7700 XT packs 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2 million per square millimeter. The B200 SXM6 integrates 208,000 million transistors on a 1,628 mm² die, reaching 127.8 million per square millimeter. The B200 has roughly 7.4 times the transistor count and a die roughly 4.7 times larger.

The compute resources are similarly lopsided. The RX 7700 XT contains 3,456 shading units, 216 texture mapping units, and 96 raster operation units. It has 54 ray tracing cores and no tensor cores listed. The B200 SXM6 has 18,944 shading units, 592 TMUs, and only 24 ROPs. It lists 592 tensor cores and no ray tracing cores. The shading unit count favors the B200 by a factor of roughly 5.5, while the TMU count favors it by a factor of 2.7. The RX 7700 XT holds the advantage in ROPs, with 96 versus 24.

Clock behavior differs substantially. The RX 7700 XT runs a base clock of 1,435 MHz, a boost clock of 2,544 MHz, and a game clock of 2,171 MHz. The B200 SXM6 has a base clock of only 120 MHz and a boost clock of 1,830 MHz. The Radeon boost clock exceeds the B200 boost clock by 714 MHz.

Memory subsystems are built for different purposes. The RX 7700 XT uses 12 GB of GDDR6 on a 192-bit bus, with memory clocked at 2,250 MHz and 18 Gbps effective. Bandwidth reaches 432.0 GB/s. The B200 SXM6 uses 180 GB of HBM3e on an 8192-bit bus, with memory at 2,000 MHz and 8 Gbps effective. Bandwidth reaches 8.19 TB/s. The B200 offers 15 times the memory capacity and roughly 19 times the bandwidth.

Pixel and texture throughput also diverge. The RX 7700 XT achieves 244.2 GPixel/s and 549.5 GTexel/s. The B200 SXM6 manages 43.92 GPixel/s and 1,083.4 GTexel/s. The Radeon is roughly 5.6 times faster in pixel rate, while the B200 is roughly 2 times faster in texture rate. Floating point performance favors the B200: 69.34 TFLOPS for FP32 and FP16 versus 35.17 TFLOPS for both on the RX 7700 XT.

API support separates the two completely. The RX 7700 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 SXM6 lists N/A for DirectX, OpenGL, and Vulkan. Power requirements reflect the B200's server orientation: 1,000 W TDP and a suggested 1,400 W PSU versus 245 W TDP and a suggested 550 W PSU for the Radeon.

Where Each One Wins

The recorded data supports distinct use-case conclusions despite the lack of direct head-to-head tests.

The AMD Radeon RX 7700 XT wins in anything involving consumer graphics APIs. Its DirectX 12 Ultimate support, Vulkan 1.4 support, and OpenGL 4.6 support make it the only one of the two that can run conventional games or desktop applications. The B200 SXM6 lists no graphics API support at all. The RX 7700 XT also provides display outputs: one HDMI 2.1a, two DisplayPort 2.1, and one USB Type-C. The B200 has no display outputs. The Radeon uses a PCIe 4.0 x16 interface, while the B200 uses PCIe 6.0 x16.

The RX 7700 XT wins in pixel throughput. Its 244.2 GPixel/s versus 43.92 GPixel/s gives it a 5.6 times advantage, which matters for rasterization-heavy workloads. The Radeon also wins on clock speeds, with a boost clock of 2,544 MHz versus 1,830 MHz.

The NVIDIA B200 SXM6 wins in raw compute throughput. Its 69.34 TFLOPS FP32 and FP16 performance is roughly 1.97 times the Radeon's 35.17 TFLOPS. The B200 wins in texture rate at 1,083.4 GTexel/s versus 549.5 GTexel/s. The B200 wins decisively in memory capacity and bandwidth: 180 GB versus 12 GB, and 8.19 TB/s versus 432.0 GB/s.

The B200 wins in transistor density, with 127.8M per square millimeter versus 81.2M per square millimeter. It also wins in tensor core presence, with 592 tensor cores versus none listed for the Radeon, indicating that the B200 targets AI and compute acceleration workloads.

The Radeon wins in physical integration for consumer systems. It is a dual-slot card with 2x 8-pin power connectors, measuring 267 mm by 135 mm by 50 mm. The B200 is an SXM module with no listed dimensions and no power connector specification, requiring a 1,400 W PSU versus 550 W.

The Radeon also wins in pixel-rate efficiency relative to its power envelope, but the data does not provide efficiency ratios. The B200 wins in raw FP32 density per watt by a narrow margin based on the recorded figures, though no such derived metric appears in the database.
