AMD Instinct MI325X vs AMD Radeon 8050S Comparison

Where Each One Wins

The AMD Instinct MI325X and the AMD Radeon 8050S occupy entirely different segments of the GPU landscape. The Instinct MI325X is a data center accelerator designed for compute workloads, while the Radeon 8050S is a mobile integrated graphics processor. The data shows no head-to-head benchmark overlap, as the MI325X has no recorded benchmarks in the database and the 8050S has two recorded results. The wins are therefore defined by architectural purpose rather than direct comparison.

The Instinct MI325X wins in raw compute throughput. Its FP32 performance is 81.72 TFLOPS, and its FP16 performance matches at 81.72 TFLOPS with a 1:1 ratio. The Radeon 8050S delivers 11.47 TFLOPS in both FP32 and FP16. The MI325X has 19,456 shading units, 1,216 texture mapping units, and a texture rate of 2,553.6 GTexel/s. The 8050S has 2,048 shading units, 128 TMUs, and a texture rate of 358.4 GTexel/s. In every raw throughput metric, the MI325X is the clear leader.

The Radeon 8050S wins in graphics-specific capabilities. It has 32 ray tracing cores, 64 ROPs, and a pixel rate of 179.2 GPixel/s. The MI325X has 0 ROPs and a pixel rate of 0 MPixel/s. The 8050S supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI325X lists N/A for all three graphics APIs. The 8050S is an active production part with display outputs that are portable device dependent, while the MI325X has no display outputs.

The 8050S also wins in efficiency. Its TDP is 55 W, while the MI325X draws 1000 W. The 8050S is an IGP with no power connectors required. The MI325X is an OAM Module with no power connectors listed, but its suggested PSU is 1400 W. The 8050S uses system shared memory, which eliminates dedicated memory power draw. The MI325X requires 256 GB of HBM3e memory with 8192-bit bus width and 6.14 TB/s bandwidth.

The Verdict

The database indicates two different buyers. The AMD Instinct MI325X targets compute-intensive environments that need massive memory and throughput. Its 256 GB HBM3e memory with 6.14 TB/s bandwidth and 81.72 TFLOPS FP32 performance position it for large-scale data center workloads. The Radeon 8050S targets mobile graphics with a 55 W TDP, ray tracing cores, and full graphics API support.

The MI325X has no benchmark scores in the database, so its percentile versus all GPUs is 50. The 8050S has an average benchmark score of 62,108, placing it in the 89th percentile versus all GPUs. The 8050S sits 0.3% above the AMD Radeon Pro W6600M, 2.5% below the AMD Radeon Pro Vega 56, 2.6% below the AMD Radeon RX 7600M, and 2.7% below the AMD Radeon RX 9060 XT LP.

The MI325X uses the CDNA 3.0 architecture on a 5 nm TSMC process. The 8050S uses RDNA 3.5 on a 4 nm TSMC process. The MI325X has 153,000 million transistors on a 1017 mm² die. The 8050S has an unknown transistor count on a 308 mm² die. The MI325X is from the Instinct (MIx) generation with an Aqua Vanjaram chip. The 8050S is from the Navi Mobile (RX 8000M) generation with a Strix Halo chip.

The MI325X releases on 2024-10-09. The 8050S releases on 2025-01-05. The MI325X predecessor is Radeon Instinct. The 8050S predecessor is Polaris Mobile. Neither has a successor listed.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between these two GPUs. The MI325X has zero recorded benchmarks, and the 8050S has two: Geekbench OpenCL at 65,818 and Geekbench Vulkan at 58,398. The average of those two scores is 62,108.

The nearest rival data for the 8050S provides context for its performance tier. The AMD Radeon Pro W6600M scores 61,896, which is 0.3% below the 8050S. The AMD Radeon Pro Vega 56 scores 63,693, which is 2.5% above the 8050S. The AMD Radeon RX 7600M scores 63,775, which is 2.6% above. The AMD Radeon RX 9060 XT LP scores 63,830, which is 2.7% above. The 8050S is essentially at parity with the Pro W6600M and within a small margin of the other three rivals.

The MI325X has no nearest rivals listed and no average benchmark score. Its percentile of 50 reflects the absence of measured performance data rather than actual performance. The FP32 figure of 81.72 TFLOPS is 7.1 times the 8050S FP32 figure of 11.47 TFLOPS. The texture rate of 2,553.6 GTexel/s is 7.1 times the 8050S texture rate of 358.4 GTexel/s.

The memory systems differ completely. The MI325X has 256 GB HBM3e with 8192-bit bus width and 6.14 TB/s bandwidth. The 8050S uses system shared memory with system dependent bandwidth. The MI325X memory clock is 1500 MHz with 6 Gbps effective. The 8050S memory clock is not specified beyond system shared.
