Architecture Differences

The two GPUs represent fundamentally different design philosophies. The RTX 5070 SUPER is a client desktop GPU built on the Blackwell 2.0 architecture with the GB205 chip. It uses GDDR7 memory and is designed for real-time rendering, featuring 50 RT cores and 200 tensor cores. Its 6400 shading units operate at a base clock of 2325 MHz with a boost of 2512 MHz, and the memory runs at 1750 MHz with 28 Gbps effective speed.

The H800 SXM5 is a server accelerator built on the Hopper architecture with the GH100 chip. It uses HBM3 memory with a much wider 5120-bit bus. The chip contains 16,896 shading units, 528 TMUs, and 528 tensor cores, but has no RT cores listed. Its clocks are significantly lower: 1095 MHz base and 1755 MHz boost, with memory at 1313 MHz or 5.3 Gbps effective. The H800 SXM5 sits in the Server Hopper generation and is a SXM module rather than a dual-slot card.

The transistor density differs notably. The RTX 5070 SUPER achieves 118.3 million transistors per mm², while the H800 SXM5 achieves 98.3 million per mm². Despite the lower density, the H800's much larger 814 mm² die holds over 2.5 times the total transistor count. The H800 SXM5 supports FP16 at 237.2 TFLOPS with a 4:1 ratio, whereas the RTX 5070 SUPER offers 32.15 TFLOPS FP16 at a 1:1 ratio, indicating the server chip's emphasis on mixed-precision workloads.

The RTX 5070 SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H800 SXM5 has no API support listed, consistent with its server orientation without a display stack. Power delivery differs as well: the RTX 5070 SUPER uses a 1x 16-pin connector with a 275 W TDP, while the H800 SXM5 uses an 8-pin EPS connector with a 700 W TDP and a suggested PSU of 1100 W.

Head-to-Head Benchmarks

The database contains a single benchmark entry for the RTX 5070 SUPER: a 3DMark Steel Nomad DX12 score of 2690. The H800 SXM5 has no recorded benchmarks, so direct numerical comparison relies on the RTX 5070 SUPER's standing among its nearest rivals. The RTX 5070 SUPER sits at the 18th percentile of all GPUs in the database. Its nearest rival is the NVIDIA Quadro K1100M with an average score of 2664, a 1% difference. The GeForce GT 1030 scores 2662 (1.1% slower), the Intel Arc Pro B50 scores 2660 (1.1% slower), and the GeForce GT 440 scores 2645 (1.7% slower).

These narrow margins indicate that in the database's recorded 3DMark Steel Nomad test, the RTX 5070 SUPER outperforms these older or lower-tier cards by only 1% to 1.7%. The H800 SXM5 has an average benchmark score of 0 and no nearest rivals, meaning the database has no comparable measurements for it. The percentile ranking for the H800 SXM5 is 50, but with no actual scores, this reflects its positional classification rather than a measurable performance result.

The H800 SXM5's FP32 compute of 59.30 TFLOPS versus the RTX 5070 SUPER's 32.15 TFLOPS suggests substantial raw throughput advantages in compute-heavy tasks. However, without matching benchmark scores, the database cannot quantify how this translates to real-world application performance. The texture rate difference is also notable: the H800 delivers 926.6 GTexel/s versus 502.4 GTexel/s for the RTX 5070 SUPER, a 84% advantage. Conversely, the RTX 5070 SUPER has a higher pixel rate at 201.0 GPixel/s versus 42.12 GPixel/s, reflecting its rendering-focused design.

The Verdict

The data indicates these are not competing products. The RTX 5070 SUPER is a client GPU with display outputs, DirectX 12 Ultimate support, and a 3DMark Steel Nomad score of 2690. The H800 SXM5 is a server accelerator with no display outputs, no API listings, and no recorded benchmark scores. The H800 SXM5 holds decisive advantages in memory capacity (80 GB versus 18 GB), memory bandwidth (3.36 TB/s versus 672.0 GB/s), FP32 compute (59.30 versus 32.15 TFLOPS), FP16 compute (237.2 versus 32.15 TFLOPS), transistor count (80,000 million versus 31,100 million), and texture rate (926.6 versus 502.4 GTexel/s).

The RTX 5070 SUPER counters with a higher pixel rate (201.0 versus 42.12 GPixel/s), higher transistor density (118.3 versus 98.3 million per mm²), support for modern graphics APIs, and a much lower TDP (275 W versus 700 W). For gaming and real-time rendering workloads where pixel throughput and API support matter, the RTX 5070 SUPER is the appropriate choice. For server-side compute, large memory footprints, and mixed-precision workloads, the H800 SXM5 is the clear selection based on the recorded specifications.
