NVIDIA B200 SXM6 vs NVIDIA RTX 4500 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the NVIDIA B200 SXM6 and the NVIDIA RTX 4500 Ada Generation. However, the database does provide an average benchmark score for the RTX 4500 Ada Generation, while the B200 SXM6 has no recorded benchmark score. This lack of comparative data means the analysis must rely on architectural specifications, memory capabilities, and the RTX 4500's position among its nearest rivals.

The RTX 4500 Ada Generation delivers an average benchmark score of 166,094 across two recorded tests: Geekbench OpenCL at 160,786 and Geekbench Vulkan at 171,401. This places it in the 97th percentile of all GPUs in the database, indicating strong performance relative to the broader GPU landscape. Its nearest rivals include the NVIDIA RTX A5500 with an average score of 165,217, which is 0.5% behind the RTX 4500. The AMD Radeon PRO W7800 scores 164,894, sitting 0.7% lower. The AMD Radeon Pro W6900X leads slightly with 168,574, a 1.5% advantage over the RTX 4500. The NVIDIA A100 PCIe 40 GB trails at 162,504, which is 2.2% behind.

The B200 SXM6 has no benchmark entries, no nearest rivals listed, and a 50th percentile ranking, which reflects the absence of measured performance data rather than an actual performance assessment. The wins counter shows zero for both parts, confirming that no direct comparison exists in the database.

Where Each One Wins

The B200 SXM6 wins decisively on raw compute capacity and memory scale. Its FP32 throughput of 69.34 TFLOPS stands significantly above the RTX 4500's 39.63 TFLOPS, a 75% advantage in single-precision floating-point performance. The FP16 figures mirror this exactly: 69.34 TFLOPS for the B200 versus 39.63 TFLOPS for the RTX 4500, with both operating at a 1:1 ratio. Texture rate also favors the B200 at 1,083.4 GTexel/s compared to 619.2 GTexel/s, a 75% lead.

Memory capacity heavily favors the B200 SXM6, which carries 180 GB of HBM3e across an 8192-bit bus, yielding 8.19 TB/s of bandwidth. The RTX 4500 Ada Generation has 24 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s. The B200's bandwidth is roughly 19 times higher, and its capacity is 7.5 times larger. The B200 also integrates 592 tensor cores, 592 texture mapping units, and 18,944 shading units, while the RTX 4500 has 240 tensor cores, 240 TMUs, and 7,680 shading units.

The RTX 4500 Ada Generation wins on pixel throughput and practical workstation features. Its pixel rate of 206.4 GPixel/s is 4.7 times higher than the B200's 43.92 GPixel/s, a result of the B200's unusually low ROP count of 24 versus 80 on the RTX 4500. Clock speeds also favor the RTX 4500: base clock of 2070 MHz and boost of 2580 MHz, compared to the B200's 120 MHz base and 1830 MHz boost. The RTX 4500 includes 60 ray tracing cores, which the B200 lacks entirely. Display outputs are present on the RTX 4500 with 4x DisplayPort 1.4a, while the B200 has no display outputs. The RTX 4500 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the B200 reports N/A for all three APIs. The RTX 4500 also fits a dual-slot form factor at 245 mm length and 112 mm height, whereas the B200 is an SXM module.

Architecture Differences

The B200 SXM6 uses the GB100 chip built on the Blackwell architecture, manufactured by TSMC on a 5 nm process. It contains 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8 million per square millimeter. The RTX 4500 Ada Generation uses the AD103 chip on the Ada Lovelace architecture, also TSMC 5 nm, but with 45,900 million transistors on a 379 mm² die, giving a density of 121.1 million per square millimeter. The B200's die is 4.3 times larger and carries 4.5 times more transistors.

Memory architecture differs fundamentally. The B200 uses HBM3e with an 8192-bit bus and 8.19 TB/s bandwidth, while the RTX 4500 uses GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. The B200's memory clock is recorded as 2000 MHz with 8 Gbps effective speed; the RTX 4500 runs at 2250 MHz with 18 Gbps effective speed. The bus width difference explains the bandwidth gap despite the RTX 4500's higher memory clock.

Core configuration diverges sharply. The B200 has 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores, with no RT cores. The RTX 4500 has 7,680 shading units, 240 TMUs, 80 ROPs, 60 RT cores, and 240 tensor cores. The B200's ROP count is unusually low for its compute scale, which directly impacts pixel rate. The RTX 4500's RT core presence enables ray tracing workloads, a capability entirely absent from the B200.

Interface and power characteristics also differ. The B200 uses PCIe 6.0 x16, while the RTX 4500 uses PCIe 4.0 x16. The B200 has a TDP of 1000 W and a suggested PSU of 1400 W; the RTX 4500 has a TDP of 210 W and a suggested PSU of 550 W. The B200's slot width is listed as SXM Module with no power connectors specified; the RTX 4500 is dual-slot with no external power connectors listed. The B200 has no display outputs; the RTX 4500 has 4x DisplayPort 1.4a.

The Verdict

The data separates these two GPUs into distinct use categories. The B200 SXM6 is built for massive compute and memory throughput: its 69.34 TFLOPS FP32, 8.19 TB/s bandwidth, and 180 GB capacity place it firmly in server and data center territory. Its 1000 W TDP, SXM module form factor, and lack of display outputs confirm it is not intended for desktop workstation use.

The RTX 4500 Ada Generation is a workstation GPU with balanced capabilities: 39.63 TFLOPS FP32, 24 GB GDDR6, 206.4 GPixel/s pixel rate, 60 RT cores, and 4x DisplayPort 1.4a outputs. Its 210 W TDP and dual-slot design make it suitable for standard workstation chassis. Its 97th percentile ranking and benchmark scores near 166,094 place it competitively against the RTX A5500 and AMD Radeon PRO W7800, with only the Radeon Pro W6900X ahead by 1.5%.

Users requiring maximum FP32 or FP16 throughput, immense memory capacity, or extremely high memory bandwidth should select the B200 SXM6. Users needing ray tracing, display outputs, standard API support, or a conventional workstation form factor should select the RTX 4500 Ada Generation. The B200's 4.7 times higher pixel rate disadvantage and absence of RT cores make it unsuitable for graphics-centric workloads, while the RTX 4500's 75% lower FP32 throughput and 19 times lower memory bandwidth limit its appeal for large-scale compute tasks. The choice hinges on whether the workload prioritizes raw compute and memory scale or graphics features and workstation integration.
