AMD Instinct MI300A vs Intel Arc Graphics 64EU Mobile Comparison

The Verdict

The AMD Instinct MI300A and Intel Arc Graphics 64EU Mobile occupy entirely different segments of the GPU market, and the recorded data confirms they are not direct competitors. The MI300A is a data center accelerator built for massive compute workloads, while the Arc Graphics 64EU Mobile is an integrated graphics solution for laptops. The MI300A delivers 61.29 TFLOPS of FP32 performance versus 1.792 TFLOPS for the Intel part, a 34.2x gap in raw floating-point throughput. The MI300A uses a 5 nm TSMC process, 153,000 million transistors on a 1017 mm² die, and 128 GB of HBM3 memory with 5.32 TB/s bandwidth. The Arc part uses Intel's 10 nm process with system-shared memory and a 65 W TDP. The MI300A carries a 750 W TDP and requires a 1150 W suggested PSU, while the Arc is an IGP with no discrete power connector. The data shows the MI300A is for server racks and AI training clusters, while the Arc Graphics 64EU Mobile is for everyday mobile computing. Neither part has benchmark scores in the database, so percentile rankings are equal at 50, but the architectural differences make any direct comparison purely academic. Choose the MI300A for compute density and HBM bandwidth; choose the Arc for low-power integrated graphics in portable devices.

Head-to-Head Benchmarks

The database lists no head-to-head benchmark entries for these two parts, and neither has individual benchmark scores. The winsA and winsB fields are both zero, indicating no recorded competitive measurements exist. However, the specification data provides clear performance indicators. The MI300A's FP32 compute of 61.29 TFLOPS is 34.2 times the Arc's 1.792 TFLOPS. The MI300A's texture rate of 1,915.2 GTexel/s is 34.2 times the Arc's 56.00 GTexel/s. The MI300A's memory bandwidth of 5.32 TB/s vastly exceeds the Arc's system-dependent bandwidth. The Arc supports FP16 at 3.584 TFLOPS (2:1), while the MI300A has no listed FP16 value. The MI300A has no pixel rate due to zero ROPs, while the Arc delivers 28.00 GPixel/s. The MI300A's clock speeds are 1000 MHz base and 2100 MHz boost, with memory at 1300 MHz (5.2 Gbps effective). The Arc runs at 300 MHz base and 1750 MHz boost, with system-shared memory. The MI300A's 14592 shading units are 28.5 times the Arc's 512. The MI300A's 912 TMUs are 28.5 times the Arc's 32. The MI300A's zero ROPs versus the Arc's 16 ROPs means the Arc handles pixel output while the MI300A does not. The MI300A's 750 W TDP is 11.5 times the Arc's 65 W TDP. The MI300A's suggested PSU of 1150 W indicates its power requirements, while the Arc has no suggested PSU listed.
