AMD Instinct MI300A vs AMD Radeon 890M Comparison

The Verdict

The AMD Instinct MI300A is a datacenter compute accelerator with no recorded benchmark scores in the database, while the AMD Radeon 890M is an integrated graphics processor with ten recorded benchmark results and an average score of 9210. The data confirms two entirely different products: the MI300A targets massive parallel compute workloads with a 750 W TDP, while the 890M targets portable devices with a 15 W TDP. The 890M has a percentile ranking of 45 against all GPUs, placing it below the 50th percentile, and its nearest rivals include the AMD Radeon Vega 8 at 9221 average score (0.1% higher), the NVIDIA GeForce GTX 960 at 9273 (0.7% higher), the NVIDIA GeForce GTX 465 at 9294 (0.9% higher), and the NVIDIA GeForce GTX 850M at 9302 (1% higher). The MI300A holds a 50th percentile ranking but has no benchmarks to substantiate performance claims. Buyers seeking an integrated GPU for portable systems should consider the 890M based on its measured results; buyers seeking a compute accelerator should evaluate the MI300A on specifications alone, since the database contains no performance measurements for it.

Where Each One Wins

The MI300A wins on raw compute specifications. Its FP32 throughput of 61.29 TFLOPS dwarfs the 890M's 5.939 TFLOPS. Its texture rate of 1,915.2 GTexel/s is more than ten times the 890M's 185.6 GTexel/s. The MI300A's memory subsystem, with 128 GB of HBM3 on an 8192-bit bus delivering 5.32 TB/s, has no equivalent in the 890M's system-shared configuration. The MI300A also uses a newer PCIe interface at 5.0 x16 versus the 890M's 4.0 x8, and it contains 153,000 million transistors versus 34,000 million. The MI300A's 750 W TDP and OAM module slot indicate a datacenter-oriented design with a suggested PSU of 1150 W.

The 890M wins on integrated functionality and measured performance. It has ten recorded benchmark scores, including a Geekbench Vulkan score of 40808 and a Geekbench OpenCL score of 37254, a Passmark G3D score of 8076, and a Passmark GPU compute score of 4157. It delivers a 92.80 GPixel/s pixel rate, which the MI300A cannot match at 0 MPixel/s. The 890M includes 16 ray tracing cores, supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and offers display outputs for portable devices. Its 15 W TDP makes it suitable for integrated use in mobile systems, while the MI300A has no display outputs and no API support. The 890M has an active production status and a release date of 2024-07-14, while the MI300A's production status is not listed. The 890M's 4 nm process node is smaller than the MI300A's 5 nm node, and its 2900 MHz boost clock exceeds the MI300A's 2100 MHz boost clock, though the MI300A has a higher base clock at 1000 MHz versus 400 MHz. The 890M's percentile ranking of 45 reflects measured performance against all GPUs, whereas the MI300A's 50th percentile ranking is based on no benchmark data. For workloads requiring display output, API support, or ray tracing, the 890M is the only option with recorded capability. For workloads requiring massive memory bandwidth, high FP32 throughput, and datacenter-class compute, the MI300A's specifications point to that role, though the database has no benchmark results to confirm its real-world performance.
