AMD Radeon RX 7600M XT vs NVIDIA B200 SXM6 Comparison

# AMD Radeon RX 7600M XT vs NVIDIA B200 SXM6

The AMD Radeon RX 7600M XT and NVIDIA B200 SXM6 occupy opposite ends of the GPU spectrum. One is a mobile gaming part with a full set of consumer APIs and a compact package; the other is a server accelerator with enormous memory, no display outputs, and a 1000 W power envelope. The recorded data shows that these products share almost nothing in terms of target workload, physical design, or benchmark coverage.

Architecture Differences

The architectural divide is substantial. The AMD Radeon RX 7600M XT uses the RDNA 3.0 architecture (codenamed Hotpink Bonefish) on a Navi 33 chip, built on TSMC's 6 nm process. The NVIDIA B200 SXM6 uses the Blackwell architecture on a GB100 chip, fabricated on TSMC's 5 nm process. Both are TSMC products, but the process nodes differ by one generation step.

The NVIDIA part is a monolithic server chip with 208,000 million transistors, while the AMD mobile GPU has 13,300 million transistors. Die sizes reflect this: 1628 mm² for the B200 SXM6 versus 204 mm² for the RX 7600M XT. Transistor density also differs, with the NVIDIA chip achieving 127.8M transistors per mm² compared to 65.2M per mm² for the AMD part.

Core counts show a similar scale difference. The B200 SXM6 has 18,944 shading units, 592 TMUs, and 24 ROPs. The RX 7600M XT has 2,048 shading units, 128 TMUs, and 64 ROPs. Notably, the NVIDIA part has 592 tensor cores and no listed RT cores, while the AMD part has 32 RT cores and no tensor cores. The AMD GPU's ROP count is higher, but its texture rate is far lower: 316.0 GTexel/s versus 1,083.4 GTexel/s for the NVIDIA part. Pixel rates also differ in the opposite direction: 158.0 GPixel/s for AMD versus 43.92 GPixel/s for NVIDIA, reflecting the B200 SXM6's compute-oriented design rather than a rasterization focus.

Memory architectures are fundamentally different. The RX 7600M XT uses 8 GB of GDDR6 with a 128-bit bus and 288.0 GB/s bandwidth. The B200 SXM6 uses 180 GB of HBM3e with an 8192-bit bus and 8.19 TB/s bandwidth. The NVIDIA part has no display outputs, while the AMD part's display outputs are listed as portable device dependent.

The B200 SXM6 is a 1000 W part with a suggested PSU of 1400 W and SXM module slot width. The RX 7600M XT is an IGP-class part at 120 W with no power connectors. The bus interfaces differ: PCIe 6.0 x16 for NVIDIA versus PCIe 4.0 x16 for AMD. The NVIDIA part succeeds Server Hopper and is succeeded by Server Rubin, while the AMD part's predecessor is Polaris Mobile.

The Verdict

The data indicates these GPUs serve entirely separate markets. The AMD Radeon RX 7600M XT is a mobile graphics solution for portable devices, with full consumer API support, a 120 W power draw, and an IGP form factor. The NVIDIA B200 SXM6 is a server accelerator with a 1000 W TDP, SXM module form factor, 180 GB of HBM3e memory, and no display outputs.

For gaming or general consumer graphics workloads, the RX 7600M XT is the only viable option in this comparison, as the B200 SXM6 lacks DirectX, OpenGL, and Vulkan support. The AMD part also has a significantly higher boost clock (2469 MHz versus 1830 MHz) and a higher pixel rate (158.0 GPixel/s versus 43.92 GPixel/s), which matters for rasterization-heavy tasks.

For compute-heavy server workloads, the B200 SXM6 is the clear choice. Its 69.34 TFLOPS FP32 performance is roughly 3.4 times the RX 7600M XT's 20.23 TFLOPS. The 8.19 TB/s memory bandwidth is approximately 28 times higher, and the 180 GB capacity dwarfs the 8 GB on the AMD part. The 592 tensor cores provide AI acceleration capability that the RX 7600M XT lacks entirely.

Benchmark coverage is one-sided. The RX 7600M XT has ten recorded benchmark scores, including 3DMark Steel Nomad DX12 (2048), Geekbench OpenCL (74,869), Geekbench Vulkan (27,793), and Passmark G3D (13,907). The B200 SXM6 has no benchmark results in the database, making direct performance comparisons impossible. Its percentile rank is 50 against all GPUs, but that is based on no recorded scores.

The 52nd percentile ranking for the RX 7600M XT places it near the middle of all GPUs. Its nearest rivals in the database are the NVIDIA GeForce GTX 670 (average score 12,773, delta -0.5%), the NVIDIA Tesla K20Xm (12,625, delta +0.7%), the NVIDIA GeForce GTX 590 (12,830, delta -0.9%), and the AMD Radeon Pro 455 (12,831, delta -0.9%). These are all older parts with similar average scores, indicating the RX 7600M XT's performance class.

The 120 W power draw of the AMD part versus 1000 W for the NVIDIA part is a defining difference. The RX 7600M XT can operate without external power connectors, while the B200 SXM6 requires a 1400 W suggested PSU. Any system design decision must account for this massive power and cooling disparity.

Specification Differences

The two GPUs differ in nearly every specification field. The RX 7600M XT uses a 6 nm process; the B200 SXM6 uses 5 nm. Transistor counts are 13,300 million versus 208,000 million. Die sizes are 204 mm² versus 1628 mm². Base clocks are 1280 MHz versus 120 MHz, and boost clocks are 2469 MHz versus 1830 MHz. The AMD part has a game clock of 2023 MHz, while the NVIDIA part has none listed.

Memory differences are extreme: 8 GB GDDR6 at 2250 MHz (18 Gbps effective) versus 180 GB HBM3e at 2000 MHz (8 Gbps effective). Bus widths are 128 bit versus 8192 bit. Bandwidth is 288.0 GB/s versus 8.19 TB/s.

Compute resources: 2,048 shading units versus 18,944; 128 TMUs versus 592; 64 ROPs versus 24; 32 RT cores versus none; no tensor cores versus 592. Pixel rates are 158.0 GPixel/s versus 43.92 GPixel/s. Texture rates are 316.0 GTexel/s versus 1,083.4 GTexel/s. FP32 performance is 20.23 TFLOPS versus 69.34 TFLOPS. FP16 performance is 40.45 TFLOPS (2:1 ratio) versus 69.34 TFLOPS (1:1 ratio).

Power and form factor: 120 W versus 1000 W TDP. The RX 7600M XT is IGP class with no power connectors; the B200 SXM6 is an SXM module with a 1400 W suggested PSU. Bus interfaces are PCIe 4.0 x16 versus PCIe 6.0 x16. Display outputs are portable device dependent versus no outputs.

API support: the AMD part has DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part lists N/A for all three. The NVIDIA part has a launch MSRP of 34,999 USD; the AMD part has no listed MSRP.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, and the B200 SXM6 has no recorded benchmark scores. The only comparable data comes from the RX 7600M XT's individual benchmark results.

The RX 7600M XT scores 2048 in 3DMark Steel Nomad DX12, 74,869 in Geekbench OpenCL, and 27,793 in Geekbench Vulkan. Passmark results include 13,907 in G3D, 7,140 in GPU Compute, 894 in G2D, 175 in DirectX 9, 137 in DirectX 11, 76 in DirectX 10, and 58 in DirectX 12. Its average benchmark score is 12,710.

The B200 SXM6's average benchmark score is 0, with no entries in the benchmark array. The database records zero wins for either side in head-to-head comparisons. This absence of data means any performance comparison must rely on architectural specifications rather than measured results.

The FP32 throughput difference is the most concrete performance indicator available. The B200 SXM6's 69.34 TFLOPS is more than triple the RX 7600M XT's 20.23 TFLOPS. Texture rate favors NVIDIA by a factor of 3.4, while pixel rate favors AMD by a factor of 3.6. These ratios reflect the different design goals: the NVIDIA part prioritizes compute throughput and memory bandwidth, while the AMD part retains higher rasterization throughput per watt.

The RX 7600M XT's nearest rival data places it within 1% of the GeForce GTX 670, Tesla K20Xm, GeForce GTX 590, and Radeon Pro 455 in average score. This positions the mobile GPU in a historical performance tier, roughly comparable to high-end parts from a decade earlier. The B200 SXM6 has no rivals listed, consistent with its unique server positioning.

The percentile rankings (52 for AMD, 50 for NVIDIA) suggest both sit near the median of all GPUs, but this is misleading. The RX 7600M XT's percentile is based on ten real benchmark scores, while the B200 SXM6's is based on no scores at all. The database treats them as statistically equivalent, but the underlying evidence is entirely different.

Given the absence of shared benchmarks and the fundamental architectural divergence, no direct performance equivalence can be established from the recorded data. The products are not competitors; they are complementary tools for different workloads. Any purchase decision would be driven by the target application, not by comparative performance metrics.
