AMD Radeon 880M vs NVIDIA H20 Comparison

Head-to-Head Benchmarks

The recorded data presents an unusual comparison scenario. The AMD Radeon 880M has a complete set of benchmark scores across multiple test suites, while the NVIDIA H20 has no recorded benchmark entries in the database. This absence of data for the H20 means that a direct score-by-score comparison cannot be constructed from the available measurements.

For the AMD Radeon 880M, the benchmark results show a wide spread across different test types. The 3DMark Steel Nomad DX12 test records a score of 535. Geekbench results are substantially higher, with OpenCL scoring 31,285 and Vulkan scoring 40,006. Passmark tests show different performance characteristics: DirectX 10 scores 31, DirectX 11 scores 73, DirectX 12 scores 32, and DirectX 9 scores 97. The Passmark G2D test records 969, G3D scores 7,615, and GPU Compute scores 3,719.

The average benchmark score for the Radeon 880M is 8,436, placing it in the 43rd percentile among all GPUs in the database. Its nearest rivals provide context for this average: the NVIDIA GeForce GTX 675MX scores 8,427 with a delta of 0.1%, the NVIDIA GeForce MX330 scores 8,458 with a delta of -0.3%, the AMD Radeon HD 8870M scores 8,462 with a delta of -0.3%, and the AMD Radeon R9 M375X scores 8,325 with a delta of 1.3%. These deltas indicate that the Radeon 880M sits within a tight cluster of mobile and older discrete GPUs, with performance differences of less than 1.5% in either direction.

The NVIDIA H20 has an average benchmark score of 0 and a percentile ranking of 50, but with no individual benchmark entries recorded. The database shows zero wins for either side in head-to-head testing, reflecting the absence of comparable measurement data. Any interpretation of relative performance must therefore rely solely on the architectural specifications recorded for each product.

Architecture Differences

The Radeon 880M and NVIDIA H20 represent fundamentally different design philosophies and market segments. The Radeon 880M uses the Strix Point chip with RDNA 3.5 architecture, belonging to the Navi III IGP generation for mobile platforms. It is manufactured on a 4 nm process at TSMC, containing 34,000 million transistors on a die size of 233 mm². This yields a transistor density of 145.9 million transistors per square millimeter.

The NVIDIA H20 uses the GH100 chip with Hopper architecture, belonging to the Server Hopper generation. It is manufactured on a 5 nm process at TSMC, containing 80,000 million transistors on a die size of 814 mm². The transistor density is 98.3 million transistors per square millimeter. The H20 is a massive server-oriented chip, more than three times the physical size of the Radeon 880M in die area and carrying more than twice the transistor count.

Clock behavior differs substantially. The Radeon 880M has a base clock of 400 MHz and a boost clock of 2,900 MHz, while the H20 operates with a base clock of 1,830 MHz and a boost clock of 1,980 MHz. The Radeon's much lower base clock with a high boost ceiling suggests aggressive power management, while the H20 runs at a more constant high frequency.

Memory configurations are entirely different in scale and type. The Radeon 880M uses system shared memory with system dependent bandwidth, meaning its memory performance relies on the host platform. The H20 uses 96 GB of HBM3 memory on a 6,144-bit bus, delivering 4.03 TB/s of bandwidth. This represents a memory subsystem designed for massive data throughput in server workloads.

Compute resources show the scale disparity. The Radeon 880M has 768 shading units, 48 texture mapping units, 16 raster operations units, and 12 ray tracing cores. The H20 has 9,984 shading units, 312 texture mapping units, 24 raster operations units, and 312 tensor cores. The H20 does not record dedicated ray tracing cores. Pixel rates are close, at 46.40 GPixel/s for the Radeon and 47.52 GPixel/s for the H20, but texture rate diverges sharply: 139.2 GTexel/s versus 617.8 GTexel/s.

Floating-point performance tells a similar story. The Radeon 880M delivers 4.454 TFLOPS for both FP32 and FP16, indicating a 1:1 ratio. The H20 delivers 39.54 TFLOPS for FP32 and 79.07 TFLOPS for FP16, reflecting a 2:1 ratio. The H20's FP16 capability is nearly 18 times the Radeon's FP32 output.

Power consumption differs by an order of magnitude. The Radeon 880M has a TDP of 15 W and is an integrated graphics processor with no power connectors. The H20 has a TDP of 500 W, is an SXM module, and requires a suggested PSU of 900 W. The bus interface also differs, with the Radeon using PCIe 4.0 x8 and the H20 using PCIe 5.0 x16.

API support is a defining difference. The Radeon 880M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The H20 lists N/A for DirectX, OpenGL, and Vulkan, indicating it is not designed for conventional graphics API workloads. The Radeon has portable device dependent display outputs, while the H20 has no display outputs at all.

The Verdict

The data indicates that these two products serve entirely different purposes and should not be considered direct competitors. The AMD Radeon 880M is an integrated GPU for mobile devices, with a 15 W TDP, system shared memory, and full support for consumer graphics APIs including DirectX 12 Ultimate and Vulkan 1.4. Its benchmark scores place it in the 43rd percentile, alongside older discrete mobile GPUs such as the GeForce GTX 675MX and MX330, with average scores clustered around 8,400 to 8,500.

The NVIDIA H20 is a server accelerator with 500 W TDP, 96 GB of HBM3 memory, and 4.03 TB/s of memory bandwidth. It lacks display outputs and conventional graphics API support, with DirectX, OpenGL, and Vulkan all listed as N/A. Its FP32 throughput of 39.54 TFLOPS and FP16 throughput of 79.07 TFLOPS position it for compute-heavy server workloads rather than graphics rendering.

Benchmark results for the H20 are absent from the database, so no measured performance comparison exists. The architectural data alone shows that the H20 delivers roughly 8.9 times the FP32 throughput of the Radeon 880M and approximately 17.7 times its FP16 output, but these are theoretical specifications, not recorded measurements. Users selecting between these products are choosing between a mobile integrated GPU and a server compute module, categories with no meaningful overlap in use cases.

Where Each One Wins

The Radeon 880M wins in scenarios requiring consumer graphics API compatibility. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, enabling conventional gaming and graphics workloads. Its 12 ray tracing cores provide hardware ray tracing support, and its 15 W TDP makes it suitable for battery-powered mobile devices. The integrated nature with PCIe 4.0 x8 and portable device dependent display outputs confirms its role in laptops and portable systems. Benchmark data shows it performs in the 43rd percentile, competitive with older discrete mobile GPUs like the GeForce GTX 675MX and MX330.

The H20 wins in server compute scenarios. Its 96 GB HBM3 memory with 4.03 TB/s bandwidth provides massive data throughput. The 312 tensor cores and FP16 performance of 79.07 TFLOPS indicate strong machine learning capability. The 9,984 shading units and 617.8 GTexel/s texture rate deliver high raw compute throughput. The SXM Module form factor, PCIe 5.0 x16 interface, and 500 W TDP designate it for data center installations. Its lack of display outputs and N/A graphics API support show it is not intended for rendering tasks. The H20's FP32 output of 39.54 TFLOPS versus the Radeon's 4.454 TFLOPS demonstrates a near nine-fold advantage in general compute throughput, though no recorded benchmark data exists to validate real-world performance.

The release timeline shows the H20 arrived first on 2024-01-31, with the Radeon 880M following on 2024-07-14. Both remain in active production. The H20's successor is listed as Server Blackwell, while the Radeon 880M has no recorded successor. The predecessor relationship also differs: the Radeon 880M succeeds Navi II IGP, and the H20 succeeds Server Ada. These lineage details reinforce the separate evolution paths of mobile integrated graphics and server accelerators.
