NVIDIA H20 vs NVIDIA RTX 2000 Ada Generation Comparison

Head-to-Head Benchmarks

The comparison between the NVIDIA H20 and the NVIDIA RTX 2000 Ada Generation is complicated by the fact that the database has no shared benchmark results for these two cards. The H20's benchmark array is empty, meaning the database has recorded zero scores for it across all tested workloads. The RTX 2000 Ada, by contrast, has ten recorded benchmark entries spanning DirectX, OpenCL, Vulkan, and compute tests.

Looking at the RTX 2000 Ada's recorded data, its strongest result comes from Geekbench Vulkan with a score of 83360, closely followed by Geekbench OpenCL at 78074. The Passmark G3D test delivers 16927 points, while Passmark GPU Compute posts 7834. The DirectX suite shows more modest numbers: Passmark DirectX 9 scores 216, DirectX 11 scores 138, DirectX 10 scores 82, and DirectX 12 scores 71. The 2D graphics test rounds out the set at 1072.

The H20's lack of recorded benchmarks means there are no direct wins for either side in the head-to-head table. The wins counter shows zero for both cards. The database's percentile ranking, however, provides some relative context. The RTX 2000 Ada sits at the 63rd percentile among all GPUs, while the H20 ranks at the 50th percentile. This suggests that the RTX 2000 Ada has demonstrated competitive positioning against the broader GPU field in the database, whereas the H20's ranking is based on its specifications rather than measured performance.

For the RTX 2000 Ada, the nearest rivals in the database include the NVIDIA Quadro K6000 with an average score of 19030, the AMD Radeon RX 6600 at 19036, the NVIDIA Tesla K80 at 18866, and the NVIDIA GeForce RTX 4050 Mobile at 19049. The delta percentages are tight: the RTX 2000 Ada trails the Quadro K6000 and Radeon RX 6600 by 0.4 percent each, sits 0.5 percent ahead of the Tesla K80, and trails the RTX 4050 Mobile by 0.5 percent. The average benchmark score for the RTX 2000 Ada is 18954, placing it within a narrow band of these comparable products.

Because the H20 has no benchmark scores and no nearest rivals listed, the data cannot support a direct performance comparison through measured results. The specification sheet, however, reveals enormous differences in compute capability. The H20's FP32 throughput is listed at 39.54 TFLOPS, while the RTX 2000 Ada delivers 12.00 TFLOPS. The H20's FP16 output reaches 79.07 TFLOPS at a 2:1 ratio, whereas the RTX 2000 Ada produces 12.00 TFLOPS at a 1:1 ratio. The texture rate also diverges sharply: 617.8 GTexel/s for the H20 versus 187.4 GTexel/s for the RTX 2000 Ada.

The pixel rate is one area where the RTX 2000 Ada actually leads the H20. The RTX 2000 Ada achieves 102.2 GPixel/s, while the H20 manages 47.52 GPixel/s. This reflects the RTX 2000 Ada's higher ROP count of 48 compared to the H20's 24 ROPs, despite the H20's much larger shading unit count of 9984 versus 2816.

The Verdict

The database indicates that the RTX 2000 Ada Generation is a measured, benchmarked product with a 63rd percentile ranking and an average score of 18954. Its nearest rivals are all within half a percentage point, showing that it performs in line with mid-range workstation and consumer cards from previous generations. The H20, with no recorded benchmarks and a 50th percentile ranking, cannot be evaluated through the same lens.

From the specification data, the H20 is clearly designed for different workloads. Its 96 GB of HBM3 memory with a 6144-bit bus and 4.03 TB/s bandwidth targets large-scale compute tasks, while the RTX 2000 Ada's 16 GB of GDDR6 on a 128-bit bus with 256.0 GB/s bandwidth suits workstation graphics and lighter compute. The H20's 500 W TDP and SXM Module form factor indicate a server-oriented accelerator, while the RTX 2000 Ada's 70 W TDP, dual-slot design, and four mini-DisplayPort 1.4a outputs make it a practical workstation card.

Users needing display outputs, DirectX 12 Ultimate support, OpenGL 4.6, or Vulkan 1.4 will find those only on the RTX 2000 Ada. The H20 lists no display outputs and marks its DirectX, OpenGL, and Vulkan APIs as N/A. The RTX 2000 Ada also includes 22 RT cores and 88 tensor cores, whereas the H20 lists tensor cores at 312 but no RT core count. The H20's PCIe 5.0 x16 interface exceeds the RTX 2000 Ada's PCIe 4.0 x8, which matters for bandwidth-sensitive server workloads.

The data supports choosing the RTX 2000 Ada for any task requiring graphics output, real-time ray tracing, or standard workstation APIs. The H20 is the choice only for massive memory-bandwidth compute workloads in a server chassis, though its lack of benchmark data means its real-world performance cannot be verified from the database.

Architecture Differences

The H20 uses the GH100 chip built on the Hopper architecture, fabricated on a 5 nm process at TSMC. The RTX 2000 Ada uses the AD107 chip on the Ada Lovelace architecture, also fabricated on a 5 nm process at TSMC. Both share the same process node and foundry, but the chips differ dramatically in scale.

The GH100 die measures 814 mm² and contains 80,000 million transistors, yielding a transistor density of 98.3 million per mm². The AD107 die is far smaller at 159 mm², containing 18,900 million transistors, which produces a higher density of 118.9 million per mm². The H20's larger die and higher transistor count reflect its server-class design, while the RTX 2000 Ada's smaller, denser die suits a workstation power envelope.

The H20's memory subsystem uses HBM3 with a 6144-bit bus width, while the RTX 2000 Ada uses GDDR6 on a 128-bit bus. The H20's memory clock runs at 1313 MHz with 5.3 Gbps effective speed, while the RTX 2000 Ada's memory clock is 2000 MHz with 16 Gbps effective. The H20's 4.03 TB/s bandwidth dwarfs the RTX 2000 Ada's 256.0 GB/s.

The H20's generation is listed as "Server Hopper (Hxx)" and its predecessor is "Server Ada," with a successor of "Server Blackwell." The RTX 2000 Ada's generation is "Workstation Ada (x000A)," with a predecessor of "Workstation Ampere" and a successor of "Blackwell PRO W." These lineage labels underscore the divergent product families.

The H20 has 312 tensor cores and 312 TMUs but no listed RT cores. The RTX 2000 Ada has 88 tensor cores, 88 TMUs, and 22 RT cores. The H20's FP16 performance at a 2:1 ratio suggests it prioritizes mixed-precision compute, while the RTX 2000 Ada's FP16 at a 1:1 ratio indicates a more balanced approach.

Specification Differences

The H20's base clock is 1830 MHz with a boost of 1980 MHz, while the RTX 2000 Ada runs a base of 1620 MHz and boost of 2130 MHz. The RTX 2000 Ada achieves a higher boost clock despite its lower TDP of 70 W versus the H20's 500 W.

Memory size differs by a factor of six: 96 GB for the H20 against 16 GB for the RTX 2000 Ada. Memory type, bus width, and bandwidth all favor the H20 substantially, as detailed above.

Shading units number 9984 on the H20 versus 2816 on the RTX 2000 Ada. TMUs are 312 versus 88, while ROPs are 24 versus 48. The H20's FP32 output of 39.54 TFLOPS exceeds the RTX 2000 Ada's 12.00 TFLOPS by a factor of roughly 3.3, and its FP16 output of 79.07 TFLOPS exceeds 12.00 TFLOPS by a factor of roughly 6.6.

The H20's texture rate of 617.8 GTexel/s is more than triple the RTX 2000 Ada's 187.4 GTexel/s, but the pixel rate reverses this, with the RTX 2000 Ada at 102.2 GPixel/s versus the H20's 47.52 GPixel/s.

Power delivery differs sharply. The H20 requires a suggested PSU of 900 W and uses an SXM Module slot width, while the RTX 2000 Ada draws only 250 W from the PSU, uses a dual-slot form factor, and requires no power connectors. The H20 has no display outputs; the RTX 2000 Ada provides four mini-DisplayPort 1.4a outputs.

The bus interface is PCIe 5.0 x16 for the H20 and PCIe 4.0 x8 for the RTX 2000 Ada. The RTX 2000 Ada measures 168 mm in length and 69 mm in height, while the H20 has no recorded dimensions.

Release dates are close: the H20 launched on 2024-01-31, and the RTX 2000 Ada launched on 2024-02-11. Both are listed as Active in production status. The RTX 2000 Ada has a launch MSRP of 649 USD.
