AMD Radeon RX 7400 vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The recorded database contains benchmark results for the AMD Radeon RX 7400 but no comparable test scores for the NVIDIA B200 SXM6. The RX 7400 has an average benchmark score of 2467 across eight tests, placing it at the 17th percentile of all GPUs. Its closest rivals in the database are the AMD Radeon 8040S with an average score of 2440 (1.1% behind), the NVIDIA GeForce 710M at 2433 (1.4% behind), the Intel HD Graphics 610 at 2425 (1.8% behind), and the NVIDIA GeForce GT 710M at 2422 (1.9% behind). These margins are narrow, within roughly two percent of the RX 7400's average.

The B200 SXM6 has no recorded benchmark scores, an average score of zero, and no nearest rivals listed. Its percentile placement of 50 reflects the absence of measured performance data rather than a tested result. The head-to-head benchmark comparison between the two products is therefore empty; the database holds no direct matchups.

Looking at the RX 7400's individual test results, the highest score comes from the Passmark G3D test at 11897, followed by Passmark G2D at 1209, Passmark GPU Compute at 5152, and Passmark DirectX 9 at 176. The DirectX 11 score is 97, the DirectX 10 score is 59, and the DirectX 12 score is 44. The 3DMark Steel Nomad DX12 test yields 1103. These figures indicate a pattern where the card performs relatively stronger in older DirectX versions and general 2D tasks compared to modern DirectX 12 workloads.

For the B200 SXM6, the lack of benchmark entries means any numerical comparison of gaming or graphics performance is impossible. The database records no wins for either product in a head-to-head context, and the wins counters for both items are zero. A direct performance ranking cannot be established from the available measurements.

Architecture Differences

The two products diverge fundamentally in their design targets. The AMD Radeon RX 7400 uses the Navi 33 chip built on RDNA 3.0 architecture, with the codename Hotpink Bonefish. It belongs to the Navi III (RX 7000) generation and is manufactured on a 6 nm process at TSMC. The chip contains 13,300 million transistors on a 204 mm² die, yielding a transistor density of 65.2 million per square millimeter.

The NVIDIA B200 SXM6 uses the GB100 chip built on Blackwell architecture, belonging to the Server Blackwell (Bxx) generation. It is also manufactured at TSMC but on a 5 nm process. The chip contains 208,000 million transistors on a 1628 mm² die, producing a transistor density of 127.8 million per square millimeter. The B200's transistor count is over fifteen times that of the RX 7400, and its die area is nearly eight times larger.

Memory architecture also differs sharply. The RX 7400 has 8 GB of GDDR6 memory on a 128-bit bus, delivering 288.0 GB/s bandwidth. The B200 SXM6 has 180 GB of HBM3e memory on an 8192-bit bus, delivering 8.19 TB/s bandwidth. The B200's memory capacity is 22.5 times larger, and its bandwidth is roughly 28.4 times higher.

Compute resources show a similar gap. The RX 7400 has 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray tracing cores. The B200 SXM6 has 18944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The B200 has over ten times as many shading units and over five times as many TMUs, though the RX 7400 has more than double the ROP count. The RX 7400 has no tensor cores listed, while the B200 has no ray tracing cores listed.

Clock speeds differ substantially. The RX 7400 has a base clock of 1452 MHz, a boost clock of 2300 MHz, and a game clock of 2200 MHz. The B200 SXM6 has a base clock of 120 MHz and a boost clock of 1830 MHz, with no game clock specified. Despite the lower base clock, the B200's much larger shader count produces higher aggregate throughput.

The process node advantage belongs to the B200 at 5 nm versus 6 nm for the RX 7400. The smaller node contributes to a higher transistor density of 127.8M per square millimeter versus 65.2M for the AMD part. Both chips are fabricated by TSMC, so foundry differences do not apply.

The Verdict

The data supports a clear separation of purpose. The AMD Radeon RX 7400 is a consumer graphics card with measured DirectX and Passmark scores, a 43 W TDP, dual-slot width, a single 6-pin power connector, and a suggested PSU of 200 W. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and provides display outputs including 1x HDMI 2.1a and 3x DisplayPort 2.1. Its release date is recorded as 2025-08-07.

The NVIDIA B200 SXM6 is a server accelerator with no display outputs, no consumer API support (DirectX, OpenGL, and Vulkan are all listed as N/A), a 1000 W TDP, an SXM module form factor, and a suggested PSU of 1400 W. Its release date is 2024-10-31, and its production status is listed as Active. The launch MSRP is 34,999 USD. The B200 has no benchmark scores in the database.

For users seeking a graphics card with recorded gaming-oriented benchmark results, the RX 7400 is the only option with data. For users seeking a high-capacity server compute accelerator with 180 GB of HBM3e memory, 8.19 TB/s bandwidth, and 592 tensor cores, the B200 SXM6 is the relevant product. The B200's 69.34 TFLOPS FP32 performance and 69.34 TFLOPS FP16 performance (1:1 ratio) far exceed the RX 7400's 16.49 TFLOPS FP32 and 32.97 TFLOPS FP16 (2:1 ratio), but the RX 7400 has higher pixel rate at 147.2 GPixel/s versus 43.92 GPixel/s for the B200.

The database records no head-to-head wins for either product, and no benchmark overlap exists to compare them directly. The choice depends entirely on the workload: consumer graphics rendering favors the RX 7400, while server-class compute favors the B200 SXM6.

Where Each One Wins

The RX 7400 wins in consumer graphics features. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the B200 SXM6 lists all APIs as N/A. The RX 7400 provides display outputs (1x HDMI 2.1a and 3x DisplayPort 2.1), whereas the B200 has no outputs. The RX 7400 also has a higher pixel rate of 147.2 GPixel/s compared to 43.92 GPixel/s for the B200, indicating an advantage in rasterization throughput per clock. Its 64 ROPs versus 24 ROPs reinforces this fill-rate advantage. The RX 7400 has 28 ray tracing cores, while the B200 lists none.

The B200 SXM6 wins in raw compute throughput and memory capacity. Its FP32 performance of 69.34 TFLOPS is 4.2 times that of the RX 7400. Its FP16 performance of 69.34 TFLOPS at a 1:1 ratio compares to the RX 7400's 32.97 TFLOPS at a 2:1 ratio, meaning the B200 maintains full FP16 throughput without the halving penalty. The B200's texture rate of 1,083.4 GTexel/s is 4.2 times the RX 7400's 257.6 GTexel/s. Memory bandwidth of 8.19 TB/s is 28.4 times higher, and memory capacity of 180 GB is 22.5 times larger. The B200 has 592 tensor cores, a feature absent from the RX 7400, making it suited for tensor-based workloads. Its PCIe 6.0 x16 interface exceeds the RX 7400's PCIe 4.0 x8. The B200's 5 nm process node and 127.8M transistors per square millimeter density also surpass the RX 7400's 6 nm node and 65.2M density.

In benchmark coverage, the RX 7400 wins because it has measured scores across DirectX 9 through DirectX 12, 3DMark Steel Nomad, and Passmark G2D, G3D, and GPU Compute tests. The B200 SXM6 has no recorded benchmark results, so its performance in those tests is unquantified. The RX 7400's nearest rivals are all within 1.9% of its average score, indicating a tightly clustered competitive set in its performance tier.

The power characteristics favor the RX 7400 for constrained environments: its 43 W TDP versus 1000 W TDP, and suggested PSU of 200 W versus 1400 W, make it deployable in standard desktop contexts. The B200 SXM6 requires server infrastructure given its SXM module form factor and absence of power connector specifications.

The release timeline differs as well, with the B200 released on 2024-10-31 and the RX 7400 on 2025-08-07. The B200's production status is Active, while the RX 7400 lists no production status. The B200's predecessor is Server Hopper and successor is Server Rubin; the RX 7400's predecessor is Navi II and successor is Navi IV.
