NVIDIA GeForce RTX 4070 GDDR6 vs NVIDIA H20 Comparison

Where Each One Wins

The recorded data separates these two NVIDIA parts into entirely different roles. The GeForce RTX 4070 GDDR6 is a consumer graphics card built for rendering pipelines, with a single 3DMark Steel Nomad DX12 result of 4334.5 points. That score places it at the 25th percentile among all GPUs in the database. Its nearest rivals in that benchmark are the Intel Iris Pro Graphics 5200 at 4360 points, 0.6% ahead, and the NVIDIA GeForce 930M at 4388 points, 1.2% ahead. The AMD FirePro W2100 sits 0.9% behind at 4295, and the NVIDIA GeForce GTX 460M trails by 1.2% at 4282. These deltas are small, which indicates the RTX 4070 GDDR6 lands in a dense cluster of mid-range scores for this particular test, despite its modern architecture.

The NVIDIA H20, by contrast, has no benchmark entries in the database at all. Its average benchmark score is listed as 0, and it holds no head-to-head results against the RTX 4070 GDDR6. The H20’s percentile versus all GPUs is 50, which is a median placement, but that figure is derived from its specification profile rather than from any recorded test runs. The data shows the H20 does not compete in the same measurement space as the RTX 4070 GDDR6. The GeForce card wins the only benchmark that exists between the two, but the H20 wins in the sense of occupying a server accelerator category where no comparable graphics workload is registered.

Where each one wins is therefore a question of domain. The RTX 4070 GDDR6 wins in any scenario that requires a display output, a DirectX 12 Ultimate feature set, or a Vulkan 1.4 API. The H20 wins in memory capacity and bandwidth, raw FP32 throughput, and tensor core count, but those advantages cannot be confirmed through benchmark scores because none are recorded. The database shows zero wins for each side in head-to-head comparisons, so the only measurable victory belongs to the RTX 4070 GDDR6 in the Steel Nomad test.

Architecture Differences

The two chips share a manufacturing process but diverge completely from there. Both use TSMC’s 5 nm node. The RTX 4070 GDDR6 is built on the AD104 chip with the Ada Lovelace architecture, part of the GeForce 40 generation. It packs 35,800 million transistors into a 294 mm² die, giving a transistor density of 121.8 million per square millimeter. The H20 uses the GH100 chip with the Hopper architecture, belonging to the Server Hopper (Hxx) generation. That die is 814 mm² and holds 80,000 million transistors, for a density of 98.3 million per square millimeter. The H20’s die is more than twice the size of the RTX 4070 GDDR6’s, and it carries more than double the transistor count, but its density is lower because the physical area grows faster than the transistor increase.

The shading unit counts differ sharply. The RTX 4070 GDDR6 has 5888 shading units, 184 texture mapping units, and 64 ROPs. The H20 has 9984 shading units, 312 TMUs, and only 24 ROPs. That ROP count is remarkably low for a chip with that many shading units, which reflects a design oriented toward compute rather than rasterization. The H20 also has 312 tensor cores, while the RTX 4070 GDDR6 has 184. The RTX 4070 GDDR6 includes 46 RT cores for ray tracing; the H20 lists no RT core count at all. The H20 does not support DirectX, OpenGL, or Vulkan, while the RTX 4070 GDDR6 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Clock behavior also separates them. The RTX 4070 GDDR6 runs at a 1920 MHz base and 2475 MHz boost. The H20 runs at 1830 MHz base and 1980 MHz boost. Lower clocks on the H20 are expected for a server part with a 500 W thermal design power. The RTX 4070 GDDR6 has a 200 W TDP. The H20’s pixel rate is 47.52 GPixel/s, far below the RTX 4070 GDDR6’s 158.4 GPixel/s, which aligns with the H20’s minimal ROP count. Texture rate favors the H20 at 617.8 GTexel/s versus 455.4 GTexel/s, driven by its larger TMU count.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between these two products. Wins are recorded as zero for both sides. The only benchmark score available for the RTX 4070 GDDR6 is the 3DMark Steel Nomad DX12 run at 4334.5 points. The H20 has no scores in any test. This makes a direct numerical comparison impossible. What the data does allow is a comparison of each product’s nearest rivals for the RTX 4070 GDDR6, and a specification-level assessment for the H20.

The RTX 4070 GDDR6’s nearest rival in the Steel Nomad test is the Intel Iris Pro Graphics 5200, which scores 4360, a 0.6% advantage. The NVIDIA GeForce 930M is 1.2% ahead at 4388. On the trailing side, the AMD FirePro W2100 is 0.9% behind at 4295, and the NVIDIA GeForce GTX 460M is 1.2% behind at 4282. These margins are narrow, under 1.5% in either direction. The RTX 4070 GDDR6’s score of 4334.5 sits essentially in the middle of that group, which is unusual for a card with 29.15 TFLOPS of FP32 performance and 12 GB of GDDR6 memory. The rivals listed are far older and far less capable in raw specs, yet their benchmark scores cluster within a few points. This suggests the Steel Nomad test may not be representative of the RTX 4070 GDDR6’s overall capabilities, or that the database’s sampling for this card is limited to a single run.

The H20 offers no such comparison. Its average benchmark score is 0, and its nearest rivals list is empty. The percentile versus all GPUs is 50, which is a neutral midpoint, but without any actual test data, that percentile carries little analytical weight. The only meaningful head-to-head statement the data supports is that the RTX 4070 GDDR6 has a recorded performance result, and the H20 does not.

Specification Differences

The memory subsystems are the most dramatic divergence. The RTX 4070 GDDR6 has 12 GB of GDDR6 memory on a 192-bit bus, delivering 480.0 GB/s bandwidth. The H20 has 96 GB of HBM3 memory on a 6144-bit bus, delivering 4.03 TB/s bandwidth. That is an 8x difference in capacity and more than an 8x difference in bandwidth. The H20’s memory clock is 1313 MHz with 5.3 Gbps effective, while the RTX 4070 GDDR6 runs at 2500 MHz with 20 Gbps effective. The higher effective data rate on the consumer card does not compensate for the vastly wider H20 bus.

FP32 compute favors the H20 at 39.54 TFLOPS versus 29.15 TFLOPS for the RTX 4070 GDDR6. FP16 performance is where the gap widens: the H20 delivers 79.07 TFLOPS with a 2:1 ratio relative to FP32, while the RTX 4070 GDDR6 delivers 29.15 TFLOPS at a 1:1 ratio. The H20’s tensor core count of 312 versus 184 on the RTX 4070 GDDR6 aligns with that FP16 advantage. The RTX 4070 GDDR6 does have RT cores, and the H20 has none listed.

Power and physical configuration differ completely. The RTX 4070 GDDR6 is a dual-slot card, 240 mm long, 110 mm tall, and 40 mm wide, with a single 16-pin power connector and a suggested 550 W PSU. The H20 is an SXM module with no listed dimensions, no power connectors, and a suggested 900 W PSU. The RTX 4070 GDDR6 uses PCIe 4.0 x16; the H20 uses PCIe 5.0 x16. Display outputs exist only on the RTX 4070 GDDR6, which has 1x HDMI 2.1 and 3x DisplayPort 1.4a. The H20 has no outputs.

Release timing is close. The H20 launched on 2024-01-31, and the RTX 4070 GDDR6 launched on 2024-08-19. The RTX 4070 GDDR6 has a launch MSRP of 599 USD. The H20 has no listed launch MSRP. Production status also differs: the RTX 4070 GDDR6 is end-of-life, while the H20 is active. The RTX 4070 GDDR6’s predecessor is GeForce 30 and its successor is GeForce 50. The H20’s predecessor is Server Ada and its successor is Server Blackwell.

The Verdict

The data supports a clear division of purpose. The GeForce RTX 4070 GDDR6 is a consumer graphics card with a complete display output suite, full graphics API support, and a recorded 3DMark Steel Nomad DX12 score of 4334.5. Its 25th percentile ranking among all GPUs places it in the lower half of the database, but it is a functional rendering product. The H20 is a server accelerator with no graphics APIs, no display outputs, and no benchmark results. Its 50th percentile is a placeholder based on specifications, not measured performance.

For any workload that requires rasterization, ray tracing, or a graphical interface, the RTX 4070 GDDR6 is the only option with recorded support. It has 46 RT cores, 184 tensor cores, and 29.15 TFLOPS of FP32 compute. Its 12 GB GDDR6 memory at 480.0 GB/s is sufficient for consumer rendering tasks. The H20 cannot be used for those tasks because it lacks the API support and output hardware.

For compute-heavy server workloads, the H20 offers 96 GB of HBM3 at 4.03 TB/s, 79.07 TFLOPS of FP16, and 312 tensor cores. Its 500 W TDP and 900 W suggested PSU reflect a data center power envelope. The RTX 4070 GDDR6’s 200 W TDP and 550 W suggested PSU indicate a far more modest installation footprint. The H20’s lack of recorded benchmarks means its real-world performance cannot be verified from the database, but its specifications put it in a different class of memory capacity and tensor throughput.

The production status confirms the trajectory. The RTX 4070 GDDR6 is end-of-life, superseded by the GeForce 50 series. The H20 is active, with the Server Blackwell generation as its successor. The RTX 4070 GDDR6 carries a launch MSRP of 599 USD, while the H20 has no listed price. Users seeking a graphics card with display outputs and API support should choose the RTX 4070 GDDR6. Users seeking a high-capacity, high-bandwidth compute accelerator with no graphics functionality should choose the H20. The benchmark data cannot compare them directly because no head-to-head results exist, but the specification differences make the intended use case unambiguous.
