AMD Radeon 8065S vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the AMD Radeon 8065S or the NVIDIA B200 SXM6. Both entries show an average benchmark score of zero and no entries in the head-to-head benchmark table. The percentile versus all GPUs is identical for both at the 50th percentile, which reflects the absence of measured performance data rather than a meaningful comparison point. With no wins recorded for either component, the head-to-head section cannot draw on direct numerical comparisons from the database.

The absence of benchmark data does not mean the two products are comparable in capability. The recorded specifications differ so dramatically that the database entries themselves serve as the primary comparative tool. The AMD part is a mobile integrated graphics processor, while the NVIDIA part is a server accelerator module. Their performance envelopes, as defined by the architecture and physical resources listed, place them in entirely different segments.

The Radeon 8065S lists a boost clock of 3000 MHz and an FP32 throughput of 15.36 TFLOPS. The B200 SXM6 lists a boost clock of 1830 MHz but an FP32 throughput of 69.34 TFLOPS, which is roughly 4.5 times higher. The B200 SXM6 also lists 18944 shading units compared to 2560 for the Radeon, a factor of approximately 7.4. The texture rate for the NVIDIA part is listed at 1,083.4 GTexel/s versus 480.0 GTexel/s for the AMD part. The pixel rate tells a different story: the Radeon lists 192.0 GPixel/s while the B200 SXM6 lists 43.92 GPixel/s, meaning the AMD part is about 4.4 times higher in that specific metric.

The memory subsystem shows the largest divergence. The B200 SXM6 lists 180 GB of HBM3e memory with a bandwidth of 8.19 TB/s across an 8192-bit bus. The Radeon 8065S lists system shared memory with a bus width and bandwidth that are system dependent. The B200 SXM6 also carries 592 tensor cores, a feature the Radeon entry does not list at all. The ray tracing core count for the Radeon is 40, while the B200 entry does not list ray tracing cores.

Where Each One Wins

Based strictly on the recorded data, the AMD Radeon 8065S wins in pixel throughput. The database lists 192.0 GPixel/s for the Radeon against 43.92 GPixel/s for the B200 SXM6. This indicates that the Radeon, with its 64 ROPs and high boost clock, is configured for rasterization output that the B200 SXM6, with only 24 ROPs, does not prioritize. The Radeon also lists a higher boost clock at 3000 MHz versus 1830 MHz, which suggests a design tuned for frequency-driven workloads rather than massive parallel arrays.

The Radeon also wins on API support breadth. It lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 SXM6 lists N/A for all three APIs. This means the Radeon is designed for client-side rendering workloads, while the B200 SXM6 is not intended for conventional graphics API operation. The Radeon also lists display outputs as portable device dependent, whereas the B200 SXM6 lists no outputs at all.

The NVIDIA B200 SXM6 wins in compute throughput. The FP32 figure of 69.34 TFLOPS is more than four times the Radeon's 15.36 TFLOPS. The FP16 figure is also 69.34 TFLOPS with a 1:1 ratio, matching the FP32 rate. The B200 SXM6 lists 18944 shading units, 592 texture mapping units, and 592 tensor cores, all of which exceed the Radeon's corresponding resources where they exist. The memory capacity of 180 GB and bandwidth of 8.19 TB/s are far beyond anything the Radeon can access through system shared memory.

The B200 SXM6 also wins on transistor count and die size. The database lists 208,000 million transistors on a 1628 mm² die for the B200, with a transistor density of 127.8 million per square millimeter. The Radeon lists a die size of 308 mm² with an unknown transistor count. The process node favors the Radeon at 4 nm versus 5 nm for the B200, both from TSMC, but the sheer scale of the B200 die gives it a resource advantage that the process node difference cannot offset.

Architecture Differences

The AMD Radeon 8065S uses the Gorgon Halo chip built on the RDNA 3.5 architecture. It belongs to the Navi Mobile generation under the RX 8000M family. The process node is 4 nm at TSMC, with a die size of 308 mm². The transistor count is listed as unknown. The B200 SXM6 uses the GB100 chip built on the Blackwell architecture, belonging to the Server Blackwell generation. Its process node is 5 nm at TSMC, with a die size of 1628 mm² and a transistor count of 208,000 million.

The Radeon lists 2560 shading units, 160 texture mapping units, 64 ROPs, and 40 ray tracing cores. It has no tensor core entry. The B200 SXM6 lists 18944 shading units, 592 texture mapping units, 24 ROPs, and 592 tensor cores. It has no ray tracing core entry. The shading unit ratio is roughly 7.4 to 1 in favor of NVIDIA, while the ROP ratio is roughly 2.7 to 1 in favor of AMD.

Memory architecture differs fundamentally. The Radeon uses system shared memory with the type also listed as system shared, a bus width of system shared, and bandwidth that is system dependent. The B200 SXM6 uses 180 GB of HBM3e with an 8192-bit bus and 8.19 TB/s bandwidth. The memory clock for the B200 is listed as 2000 MHz with 8 Gbps effective speed. The Radeon memory clock is listed as system shared.

Clock behavior diverges sharply. The Radeon base clock is 1295 MHz with a boost of 3000 MHz, a boost ratio of about 2.3 times the base. The B200 base clock is 120 MHz with a boost of 1830 MHz, a boost ratio of about 15.25 times the base. The B200 is designed to idle at very low frequencies and scale up under load, while the Radeon maintains a relatively high baseline.

The bus interface differs as well. The Radeon uses PCIe 5.0 x16, while the B200 SXM6 uses PCIe 6.0 x16. Power delivery shows the Radeon as an IGP with no power connectors and a TDP of 55 W, while the B200 SXM6 is an SXM module with a TDP of 1000 W and a suggested PSU of 1400 W. The Radeon predecessor is listed as Polaris Mobile, while the B200 predecessor is Server Hopper. The B200 successor is Server Rubin, while the Radeon has no successor listed.

The Verdict

The database shows two products designed for different tasks. The AMD Radeon 8065S is a mobile integrated graphics processor with a 55 W TDP, system shared memory, and support for client graphics APIs. Its high pixel rate of 192.0 GPixel/s and boost clock of 3000 MHz point toward rasterization and display-driven workloads in portable devices. Its small die size of 308 mm² and 4 nm process node indicate a power-efficient design.

The NVIDIA B200 SXM6 is a server accelerator module with a 1000 W TDP and a 1400 W suggested PSU. Its 69.34 TFLOPS FP32 throughput, 592 tensor cores, 18944 shading units, and 180 GB of HBM3e memory with 8.19 TB/s bandwidth position it for compute-heavy server workloads. The absence of display outputs and graphics API support confirms it is not intended for client rendering.

The data indicates that the B200 SXM6 is the stronger compute device by a wide margin, with more than four times the FP32 throughput and more than seven times the shading units. The Radeon 8065S is the stronger rasterization device by the pixel rate metric, with more than four times the pixel throughput. The Radeon also supports graphics APIs and display outputs, which the B200 does not.

The recorded data does not include any benchmark scores, so the verdict rests on the specification differences. Users requiring server-class parallel compute with large memory capacity should select the B200 SXM6. Users requiring an integrated graphics solution for a portable device with standard graphics API support should select the Radeon 8065S. The 55 W TDP of the Radeon versus the 1000 W TDP of the B200 further separates the intended deployment environments. The B200 launch MSRP is 34,999 USD.
