AMD Instinct MI300A vs AMD Radeon 740M Comparison

Where Each One Wins

The AMD Instinct MI300A and AMD Radeon 740M occupy opposite ends of the GPU spectrum, and the recorded data makes that split explicit. The MI300A is an accelerator-class part with no display outputs, no graphics API support, and no benchmark scores in the database. The Radeon 740M is an integrated graphics processor with active production status, two recorded benchmark scores, and a percentile ranking above half of all tracked GPUs.

The MI300A wins in raw compute capacity by every measurable specification. Its FP32 throughput is 61.29 TFLOPS versus 2.867 TFLOPS for the Radeon 740M, a 21.4x advantage. Texture rate stands at 1,915.2 GTexel/s versus 44.80 GTexel/s, approximately 42.8x higher. The MI300A also carries 128 GB of HBM3 memory with 5.32 TB/s of bandwidth across an 8192-bit bus, while the Radeon 740M relies on system shared memory with bandwidth described only as system dependent. The MI300A has 14,592 shading units and 912 TMUs, compared to 256 shading units and 16 TMUs on the 740M.

The Radeon 740M wins in the practical categories that the MI300A simply does not address. It has 8 ROPs, a 22.40 GPixel/s pixel rate, and 4 ray tracing cores. The MI300A lists 0 ROPs, 0 MPixel/s pixel rate, and no ray tracing cores. The 740M supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300A reports N/A for all three APIs. The 740M has a 45 W TDP versus 750 W for the MI300A, and the 740M is an IGP slot width while the MI300A is an OAM Module. The MI300A has no display outputs; the 740M has motherboard dependent outputs.

The benchmark data only exists for the Radeon 740M. It scores 10,172 in Geekbench OpenCL and 15,568 in Geekbench Vulkan, with an average benchmark score of 12,870. The MI300A has no recorded benchmarks, no average score, and no nearest rivals in the database. This means the MI300A cannot be ranked against competitors, while the 740M holds the 53rd percentile among all GPUs.

The Verdict

The database shows two products with no overlap in intended function. The AMD Instinct MI300A is a compute accelerator built for massive parallel workloads, evidenced by its 153,000 million transistors, 1017 mm² die, and 750 W TDP. It has no graphics output capability, no consumer API support, and no benchmark entries. The AMD Radeon 740M is an integrated GPU for mainstream systems, with 20,900 million transistors on a 137 mm² die, a 45 W TDP, and active production.

Anyone selecting between these two based on the recorded data must decide between compute density and graphics functionality. The MI300A delivers 61.29 TFLOPS FP32, 5.32 TB/s memory bandwidth, and 128 GB of HBM3. The Radeon 740M delivers 2.867 TFLOPS FP32, system shared memory, and full graphics API support including ray tracing.

The MI300A has no benchmark scores, so its performance cannot be compared to the 740M numerically. The 740M has two benchmark scores and sits at the 53rd percentile, with nearest rivals including the AMD Radeon RX 580 (0.4% higher average score) and AMD FirePro W5100 (0.2% lower). The MI300A has zero wins and zero losses in head-to-head comparisons because no such comparisons exist in the database.

The verdict follows the data: the MI300A is for compute acceleration in server or data center contexts, the Radeon 740M is for graphics rendering in client systems. The 740M is the only one of the two with measurable graphics performance, and the MI300A is the only one with accelerator-scale memory and throughput.

Head-to-Head Benchmarks

The headToHeadBenchmarks field in the database is empty, meaning no direct benchmark comparison has been recorded between the MI300A and the Radeon 740M. The MI300A has no benchmark entries at all, while the Radeon 740M has exactly two.

In Geekbench OpenCL, the Radeon 740M scores 10,172. In Geekbench Vulkan, it scores 15,568. These are the only performance numbers available for either product. The MI300A cannot be scored in these tests because it lacks the graphics APIs those benchmarks require. Its DirectX, OpenGL, and Vulkan support are all listed as N/A.

The Radeon 740M's average benchmark score is 12,870. Its nearest rival, the AMD Radeon RX 580, averages 12,928, which is 0.4% higher. The AMD FirePro W5100 scores 12,847, 0.2% lower. The AMD Radeon Pro 455 scores 12,831, 0.3% lower. The NVIDIA GeForce GTX 590 scores 12,830, 0.3% lower. These deltas place the 740M squarely in the middle of a small cluster of comparable GPUs.

For the MI300A, the only comparable data points are its raw specifications. Its FP32 output of 61.29 TFLOPS is 21.4x the 740M's 2.867 TFLOPS. Its texture rate of 1,915.2 GTexel/s is 42.8x the 740M's 44.80 GTexel/s. Its memory bandwidth of 5.32 TB/s has no equivalent on the 740M because that product uses system shared memory with bandwidth dependent on the host system.

The pixel rate comparison runs the opposite direction. The MI300A has 0 MPixel/s and 0 ROPs. The Radeon 740M has 22.40 GPixel/s and 8 ROPs. The MI300A is not designed to rasterize pixels, and its specifications confirm that. The 740M is designed for exactly that task.
