AMD Radeon RX 7600M vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The recorded data provides a single benchmark result for the AMD Radeon RX 7600M: a Geekbench OpenCL score of 63,775. The NVIDIA H20 has no benchmark entries in the database, which means direct numeric comparison between the two cards is limited to architectural specifications rather than measured performance outcomes.

The RX 7600M's Geekbench OpenCL score places it at the 89th percentile among all GPUs tracked in the database. Its nearest rivals show how tightly clustered this performance level is: the AMD Radeon RX 9060 XT LP scores 63,830, a 0.1% advantage over the RX 7600M; the NVIDIA CMP 30HX scores 63,842, also 0.1% ahead; the AMD Radeon Pro Vega 56 scores 63,693, which is 0.1% behind; and the AMD Radeon Pro WX 9100 leads by 0.7% with a score of 64,212. This grouping indicates that the RX 7600M sits in a highly competitive performance band where margin of error between cards is minimal.

The NVIDIA H20, by contrast, has an average benchmark score of zero and a 50th percentile ranking. The absence of benchmark data for the H20 means it cannot be placed in the same comparative framework as the RX 7600M. The H20's nearest rivals list is empty, and its wins tally is zero in the head-to-head record. This does not indicate that the H20 is a weak performer; it indicates that the database lacks measured results for this specific server-grade part.

In terms of raw compute specifications, the H20 delivers 39.54 TFLOPS of FP32 throughput, which is 2.29 times the RX 7600M's 17.27 TFLOPS. For FP16, the H20 reaches 79.07 TFLOPS versus 34.55 TFLOPS for the RX 7600M, a 2.29x advantage as well. The H20 also leads in texture rate with 617.8 GTexel/s against 269.9 GTexel/s. However, the RX 7600M counters in pixel rate: 154.2 GPixel/s versus 47.52 GPixel/s for the H20, a 3.25x advantage for the mobile AMD part. This is explained by the ROP counts: the RX 7600M has 64 ROPs while the H20 has only 24.

Memory bandwidth is another major differentiator. The H20's HBM3 memory subsystem provides 4.03 TB/s of bandwidth across a 6144-bit bus, compared to the RX 7600M's 256.0 GB/s over a 128-bit GDDR6 interface. That is a 15.7x bandwidth advantage for the H20. The H20 carries 96 GB of memory, twelve times the 8 GB on the RX 7600M.

The H20's shading unit count of 9,984 is 5.57 times the RX 7600M's 1,792. Texture mapping units follow a similar pattern: 312 on the H20 versus 112 on the RX 7600M, a 2.79x lead. The H20 also integrates 312 tensor cores, while the RX 7600M has none listed. Conversely, the RX 7600M has 28 ray tracing cores; the H20's ray tracing core count is not recorded in the database.

The Verdict

The data describes two fundamentally different products with different intended deployment contexts. The AMD Radeon RX 7600M is a mobile GPU with an integrated form factor (IGP slot width), no power connectors, and a 90 W TDP. The NVIDIA H20 is a server-class SXM module with a 500 W TDP and a 900 W suggested power supply. These are not direct competitors in the traditional sense.

For users constrained by the database's measured results, the RX 7600M has the advantage of being a verified performer: its Geekbench OpenCL score of 63,775 places it at the 89th percentile across all GPUs. The H20 has no recorded benchmark score, so its percentile of 50 reflects missing data rather than measured capability. In a pure data-availability sense, the RX 7600M is the only card of the two with a quantifiable performance ranking.

For compute-heavy workloads that can utilize the H20's larger memory pool and higher FP32/FP16 throughput, the specification sheet favors the H20. Its 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16 figures are more than double the RX 7600M's corresponding values. The 96 GB HBM3 memory with 4.03 TB/s bandwidth is in a different class entirely from the RX 7600M's 8 GB GDDR6 at 256.0 GB/s.

The RX 7600M wins on pixel throughput and ray tracing support. Its 154.2 GPixel/s pixel rate is over three times the H20's 47.52 GPixel/s, and its 28 ray tracing cores provide hardware acceleration that the H20 does not list. The RX 7600M also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the H20 lists N/A for all three graphics APIs, which is consistent with a compute-focused server accelerator that has no display outputs.

Where Each One Wins

The RX 7600M wins in scenarios that demand graphics rendering and mobile deployment. Its 64 ROPs and 154.2 GPixel/s pixel fill rate indicate strength in rasterization-heavy tasks. The 28 ray tracing cores enable hardware-accelerated ray-traced effects. The 90 W TDP and integrated form factor with no power connectors make it suitable for portable systems. The PCIe 4.0 x16 interface, while a generation behind the H20's PCIe 5.0 x16, is standard for mobile GPUs. The card's DirectX 12 Ultimate support and Vulkan 1.4 compatibility mean it can run modern gaming and graphics workloads. Its 8 GB GDDR6 memory at 256.0 GB/s is sufficient for mainstream resolutions, and its 17.27 TFLOPS FP32 throughput is respectable for a mobile part.

The H20 wins in compute-dense, memory-hungry server environments. Its 96 GB HBM3 memory with 4.03 TB/s bandwidth is suited for large datasets that would not fit in the RX 7600M's 8 GB frame buffer. The 9,984 shading units and 312 tensor cores give it massive parallel compute capacity. The 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16 numbers position it for high-throughput numeric workloads. The 312 texture mapping units and 617.8 GTexel/s texture rate support complex shader and convolution operations. The 500 W TDP and SXM module form factor indicate a data center installation profile. The PCIe 5.0 x16 bus doubles the theoretical interface bandwidth of the RX 7600M's PCIe 4.0 x16 connection. The 5 nm process node gives it a transistor density of 98.3M per square millimeter across an 814 mm² die, compared to the RX 7600M's 6 nm process with 65.2M per square millimeter on a 204 mm² die.

The H20's 80,000 million transistors dwarf the RX 7600M's 13,300 million, a 6.02x difference. The H20's 6144-bit memory bus is 48 times wider than the RX 7600M's 128-bit bus. These architectural gaps translate directly to the H20's dominance in memory-bound and massively parallel workloads. The RX 7600M counters with a 3.25x pixel rate advantage, which reflects its design priority for display output and graphics rendering.
