Analysis: AMD Radeon 8065S vs NVIDIA H20

The Verdict

The recorded data positions these two accelerators as fundamentally different tools. The AMD Radeon 8065S is a mobile integrated graphics processor built on RDNA 3.5, while the NVIDIA H20 is a server-focused SXM module built on Hopper. Neither device has recorded benchmark scores in the database, and both hold a 50th percentile ranking against all GPUs, so the comparison rests entirely on architectural and specification differences. The AMD Radeon 8065S suits portable devices that need modern graphics API support and a full display output path. The NVIDIA H20 targets compute-heavy server environments where memory capacity, tensor throughput, and raw FP32/FP16 performance dominate. There is no overlap in physical design: the 8065S is an IGP with no power connectors, while the H20 is a 500 W SXM module requiring a 900 W suggested power supply.

Architecture Differences

The AMD Radeon 8065S uses the Gorgon Halo chip, built on a 4 nm process at TSMC with a die size of 308 mm². Its architecture is RDNA 3.5, falling into the Navi Mobile (RX 8000M) generation. The NVIDIA H20 uses the GH100 chip, built on a 5 nm process at TSMC, with a die size of 814 mm² and 80,000 million transistors, giving a transistor density of 98.3M per mm². The H20 belongs to the Server Hopper (Hxx) generation and is the successor to Server Ada, with Server Blackwell listed as its successor. The 8065S lists Polaris Mobile as its predecessor.

The AMD part carries 2560 shading units, 160 texture mapping units, 64 ROPs, and 40 ray tracing cores. It has no dedicated tensor core field. The NVIDIA H20 carries 9984 shading units, 312 TMUs, 24 ROPs, and 312 tensor cores. Its ray tracing core field is not listed. The H20 uses HBM3 memory totaling 96 GB across a 6144-bit bus, with a bandwidth of 4.03 TB/s and memory clocks rated at 1313 MHz (5.3 Gbps effective). The AMD 8065S uses system shared memory, with bus width, type, and size all marked as system dependent. Its memory clock is likewise system shared. The AMD part reports pixel rate of 192.0 GPixel/s and texture rate of 480.0 GTexel/s. The NVIDIA part reports 47.52 GPixel/s and 617.8 GTexel/s.

Specification Differences

The two devices differ across nearly every recorded specification. The AMD Radeon 8065S uses RDNA 3.5 architecture on a 4 nm process, while the NVIDIA H20 uses Hopper on a 5 nm process. Die size is 308 mm² for the AMD part and 814 mm² for the NVIDIA part. Transistor count is unknown for the AMD part and 80,000 million for the NVIDIA part. Transistor density is not listed for the AMD part and is 98.3M per mm² for the NVIDIA part. Clock speeds differ: the 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz, while the H20 has a base clock of 1830 MHz and a boost clock of 1980 MHz. Memory configurations are entirely different: system shared for the AMD part versus 96 GB HBM3 with 6144-bit bus and 4.03 TB/s bandwidth for the NVIDIA part.

Shading units are 2560 versus 9984. TMUs are 160 versus 312. ROPs are 64 versus 24. Ray tracing cores are 40 on the AMD part and not listed for the NVIDIA part.

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for these two devices, and neither has an average benchmark score or nearest rivals listed. The comparison must be drawn from the specification fields. The NVIDIA H20 leads decisively in compute throughput. Its FP32 figure of 39.54 TFLOPS is 2.57 times the 15.36 TFLOPS of the AMD 8065S. In FP16, the H20 delivers 79.07 TFLOPS, which is 5.15 times the 15.36 TFLOPS of the AMD part. Texture rate favors the H20 at 617.8 GTexel/s versus 480.0 GTexel/s, a 1.29 times advantage. The H20 also dominates memory bandwidth at 4.03 TB/s, but the AMD part uses system shared memory with bandwidth listed as system dependent, so no direct ratio is available.

The AMD Radeon 8065S holds advantages in specific rasterization metrics. Its pixel rate of 192.0 GPixel/s is 4.04 times the 47.52 GPixel/s of the H20. Its boost clock of 3000 MHz exceeds the H20 boost clock of 1980 MHz by 51.5 percent. The AMD part also carries 64 ROPs versus 24 on the NVIDIA part, a 2.67 times advantage. Base clock favors the H20 at 1830 MHz versus 1295 MHz on the AMD part. The AMD part supports three graphics APIs, while the H20 lists none. The AMD part has 40 ray tracing cores, while the H20 has no ray tracing core count listed.

Where Each One Wins

The AMD Radeon 8065S wins in scenarios that demand high pixel throughput and modern graphics API compatibility. Its 192.0 GPixel/s pixel rate and 64 ROPs indicate strong fill-rate capabilities for rasterization workloads. The 3000 MHz boost clock supports responsive graphics execution. The DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support make it suitable for client-side rendering tasks. Its 55 W TDP with no power connectors and IGP slot width fit portable device integration, with display outputs described as portable device dependent. The 40 ray tracing cores provide hardware ray tracing capability, which the H20 does not list.

The NVIDIA H20 wins in compute-dense server workloads. Its 39.54 TFLOPS FP32 and 79.07 TFLOPS FP16 deliver 2.57 times and 5.15 times the respective AMD figures. The 312 tensor cores indicate a hardware path for tensor operations, which the AMD part does not list. The 96 GB HBM3 memory with 4.03 TB/s bandwidth provides a large, high-speed memory pool, though the AMD part's system shared memory makes direct capacity comparison impossible. The 9984 shading units and 312 TMUs support heavy parallel workloads. The 500 W TDP and 900 W suggested power supply confirm its data-center positioning. The H20's 24 ROPs and 47.52 GPixel/s pixel rate are lower than the AMD part, but the H20 is not designed for rasterization output, as its no-output display configuration indicates. The H20's 814 mm² die and 80,000 million transistors show a larger silicon investment aimed at compute scaling rather than graphics pipeline throughput.
