AMD Radeon 740M vs NVIDIA H20 Comparison

AMD Radeon 740M is an integrated graphics processor built on the RDNA 3.0 architecture, using the Phoenix2 chip on a 4 nm TSMC process. NVIDIA H20 is a server accelerator based on the Hopper architecture, using the GH100 chip on a 5 nm TSMC process. The two devices target completely different segments: one is an IGP for mainstream laptops, the other is a high-power compute module. Benchmark data in the database is limited for the H20, with no recorded scores, while the 740M has two recorded OpenCL and Vulkan results.

Where Each One Wins

The AMD Radeon 740M wins in the only direct benchmark comparisons that exist in the database. It records a Geekbench OpenCL score of 10172 and a Geekbench Vulkan score of 15568, giving it an average benchmark score of 12870. The NVIDIA H20 has no benchmark entries, so its average score is recorded as 0. In every measured category, the 740M is ahead because the H20 has no recorded data.

The 740M also wins on the basis of availability of consumer-facing features. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the H20 lists N/A for all three graphics APIs. The 740M is a production-active IGP with a 45 W TDP, designed to fit into a motherboard-dependent display output configuration. The H20 is a 500 W SXM module with no display outputs at all.

The H20 wins in raw compute capacity and memory resources. It delivers 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16, compared to 2.867 TFLOPS for both FP32 and FP16 on the 740M. The H20 has 96 GB of HBM3 memory with 4.03 TB/s bandwidth, while the 740M relies on system-shared memory with bandwidth described as system dependent. These are not measured benchmark wins, but they are specification advantages that indicate the H20 is built for a different workload class.

The Verdict

The data indicates that the AMD Radeon 740M is the only one of the two with any recorded benchmark performance. Its 53rd percentile ranking among all GPUs and its average score of 12870 place it near the AMD FirePro W5100, which scores 12847, and the AMD Radeon Pro 455, which scores 12831. It is 0.2% ahead of the FirePro W5100 and 0.3% ahead of both the Radeon Pro 455 and the NVIDIA GeForce GTX 590. The Radeon RX 580 sits 0.4% ahead of the 740M.

The NVIDIA H20 cannot be evaluated on the same benchmark scale because the database contains no scores for it. Its 50th percentile ranking appears to be a default or placeholder value rather than a measured result. Anyone choosing between these two for a graphics workload would select the 740M, as it has actual performance data and full graphics API support. Anyone choosing for a server compute role would select the H20 based on its memory capacity and FP16 throughput, but the database does not contain benchmark evidence to quantify that advantage.

The 740M is the practical pick for any system requiring display output, DirectX 12 Ultimate support, or Vulkan rendering. The H20 is the practical pick for a headless compute node, given its 96 GB HBM3 pool and 312 tensor cores, but no measured scores back that choice in this database.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database, so no direct comparison scores exist between the AMD Radeon 740M and NVIDIA H20. The nearest comparable data comes from the 740M's rival list, which shows how it performs against older discrete GPUs.

The 740M's average benchmark score of 12870 is 0.2% higher than the AMD FirePro W5100's 12847. It is 0.3% higher than the AMD Radeon Pro 455's 12831 and the NVIDIA GeForce GTX 590's 12830. The AMD Radeon RX 580 is the only rival ahead, with an average score of 12928, which is 0.4% above the 740M.

In individual tests, the 740M scores 10172 in Geekbench OpenCL and 15568 in Geekbench Vulkan. The Vulkan result is substantially higher than the OpenCL result, indicating that the RDNA 3.0 IGP performs better under the Vulkan API in this workload. The H20 has no equivalent scores, so no percentage difference can be calculated between the two devices.

Architecture Differences

The AMD Radeon 740M uses the Phoenix2 chip on a 4 nm TSMC process, with 20,900 million transistors on a 137 mm² die. The transistor density is 152.6 million per mm². The NVIDIA H20 uses the GH100 chip on a 5 nm TSMC process, with 80,000 million transistors on an 814 mm² die. The transistor density is 98.3 million per mm². The H20 has roughly four times the transistor count and a die about six times larger, but the 740M packs transistors more densely because of its smaller node.

The 740M is a graphics-first architecture, RDNA 3.0, with 256 shading units, 16 texture mapping units, 8 render output units, and 4 ray tracing cores. It has no tensor cores. The H20 is a compute-first architecture, Hopper, with 9984 shading units, 312 texture mapping units, 24 render output units, and 312 tensor cores. It has no listed ray tracing cores. The H20's shading unit count is roughly 39 times higher, and its texture mapping unit count is nearly 20 times higher.

The two also differ in clock strategy. The 740M has an 800 MHz base clock and a 2800 MHz boost clock. The H20 has an 1830 MHz base clock and a 1980 MHz boost clock. The 740M boosts much higher, but the H20 has far more execution resources. The 740M's FP16 throughput matches its FP32 at 2.867 TFLOPS, a 1:1 ratio. The H20's FP16 throughput is 79.07 TFLOPS, exactly double its FP32 of 39.54 TFLOPS, a 2:1 ratio.

The 740M is a PCIe 4.0 x8 device and an IGP, so it has no power connectors and its display outputs are motherboard dependent. The H20 is a PCIe 5.0 x16 SXM module with no display outputs, and it carries a 500 W TDP with a suggested power supply of 900 W.

Specification Differences

The most visible specification difference is memory. The 740M uses system-shared memory with a system-shared bus width and system-dependent bandwidth. The H20 has 96 GB of HBM3 on a 6144 bit bus with 4.03 TB/s bandwidth. The H20's memory clock is listed as 1313 MHz with 5.3 Gbps effective speed, while the 740M's memory clock is listed as system shared.

The compute resources differ sharply. The 740M has 256 shading units, 16 TMUs, 8 ROPs, and 4 ray tracing cores. The H20 has 9984 shading units, 312 TMUs, 24 ROPs, and 312 tensor cores. The 740M has no tensor cores, and the H20 has no ray tracing cores listed.

The 740M's pixel rate is 22.40 GPixel/s and its texture rate is 44.80 GTexel/s. The H20's pixel rate is 47.52 GPixel/s and its texture rate is 617.8 GTexel/s. The H20 is roughly twice as fast in pixel throughput and nearly 14 times as fast in texture throughput.

Power and physical format differ completely. The 740M is a 45 W IGP with no power connectors and a slot width of IGP. The H20 is a 500 W SXM module with a suggested power supply of 900 W and a slot width of SXM Module. The 740M uses a PCIe 4.0 x8 interface, while the H20 uses PCIe 5.0 x16.

The 740M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H20 lists N/A for all three. The 740M was released on January 30, 2024, and the H20 on January 31, 2024, one day apart. Both are marked as active in production. Neither has a launch MSRP recorded in the database.
