AMD Instinct MI325X vs Intel Arc G3 Extreme Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the AMD Instinct MI325X and the Intel Arc G3 Extreme. Both products have an average benchmark score of zero and no nearest rivals listed, which means no direct performance comparison can be established from the available measurements. The AMD part holds a percentile rank of 50 among all GPUs, and the Intel part holds the same percentile rank of 50. With zero wins recorded for either side, the data does not indicate a performance advantage for either product in any tested workload.

The absence of benchmark data is notable given the extreme disparity in raw compute specifications. The AMD Instinct MI325X delivers 81.72 TFLOPS of FP32 performance, while the Intel Arc G3 Extreme delivers 7.680 TFLOPS of FP32 performance. That difference of roughly 10.6 times in theoretical single-precision throughput would suggest a massive advantage for the AMD part, but without actual benchmark scores, such an inference remains speculative. The FP16 figures show a different ratio depending on the architecture: the AMD part achieves 81.72 TFLOPS with a 1:1 ratio, while the Intel part achieves 15.36 TFLOPS with a 2:1 ratio, meaning the Intel hardware can process FP16 at double its FP32 rate.

Texture and pixel throughput also diverge sharply. The AMD Instinct MI325X reports a texture rate of 2,553.6 GTexel/s and a pixel rate of 0 MPixel/s, which reflects its compute-oriented design with no raster output units. The Intel Arc G3 Extreme reports 120.0 GTexel/s and 60.00 GPixel/s, indicating a conventional graphics pipeline with 24 ROPs. The AMD part has 19,456 shading units and 1,216 texture mapping units, while the Intel part has 1,536 shading units and 48 TMUs. These structural differences confirm that the two products target entirely different workloads, but the database contains no measured results to quantify real-world performance.

The Verdict

The data shows that these two products cannot be directly compared through benchmark scores, as none exist in the database. The AMD Instinct MI325X is a dedicated accelerator with no display outputs, no DirectX support, no OpenGL support, and no Vulkan support. The Intel Arc G3 Extreme is an integrated graphics processor with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support. The AMD part consumes 1000 W and requires a 1400 W suggested power supply, while the Intel part consumes 80 W and has no suggested PSU requirement.

For workloads that demand massive compute throughput, the AMD Instinct MI325X presents the only viable option based on its specifications. For systems that need integrated graphics with API support and low power draw, the Intel Arc G3 Extreme is the clear choice. The database records no benchmark evidence that either product outperforms the other in any shared workload, so the verdict rests entirely on specification differences. The AMD part targets server and accelerator environments, evidenced by its OAM module slot width and lack of power connectors, while the Intel part targets portable devices, as indicated by its IGP bus interface and portable-device-dependent display outputs.

Where Each One Wins

The AMD Instinct MI325X wins in every category of raw compute throughput. Its FP32 performance of 81.72 TFLOPS is over ten times the Intel part's 7.680 TFLOPS. Its FP16 performance of 81.72 TFLOPS at a 1:1 ratio exceeds the Intel part's 15.36 TFLOPS at a 2:1 ratio. The texture rate of 2,553.6 GTexel/s is more than 21 times the Intel part's 120.0 GTexel/s. Memory capacity of 256 GB of HBM3e with an 8192-bit bus and 6.14 TB/s bandwidth dwarfs the Intel part's system-shared memory with system-dependent bandwidth. The AMD part also uses a 5 nm process from TSMC with 153,000 million transistors on a 1017 mm² die, while the Intel part's transistor count and die size are unknown, though it uses a 3 nm process from Intel.

The Intel Arc G3 Extreme wins in areas related to graphics output and software compatibility. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the AMD part reports N/A for all three APIs. The Intel part has 24 ROPs and delivers 60.00 GPixel/s of pixel throughput, while the AMD part has zero ROPs and delivers 0 MPixel/s. The Intel part has 12 ray tracing cores, while the AMD part lists no RT cores. The Intel part operates with a base clock of 300 MHz and a boost clock of 2500 MHz, while the AMD part runs at 1000 MHz base and 2100 MHz boost. The Intel part is an IGP with a 3 nm process, while the AMD part is an OAM module with a 5 nm process.
