AMD Instinct MI300A vs AMD Radeon 760M Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark results between the AMD Instinct MI300A and the AMD Radeon 760M. The MI300A has an empty benchmark array, meaning no scores were captured for it in the database. The Radeon 760M, by contrast, has ten recorded benchmark entries spanning DirectX tests, OpenCL, Vulkan, and Passmark suites. Its average benchmark score is 6019, placing it in the 35th percentile of all GPUs. The MI300A holds a 50th percentile ranking with an average benchmark score of zero, which reflects the absence of measured results rather than a lack of capability.

The Radeon 760M's scores show a clear pattern across the Passmark suite. The DirectX 9 test produced the highest Passmark result at 65, followed by DirectX 11 at 52, and DirectX 12 at 25. The DirectX 10 test scored 19. The Passmark G3D score reached 5310, while the G2D score was 890. Compute performance measured 2840 in the Passmark GPU compute test. The Geekbench results were substantially higher in absolute terms, with OpenCL scoring 20255 and Vulkan scoring 30336. The 3DMark Steel Nomad DX12 test produced a score of 400.

The nearest rivals for the Radeon 760M in the database are tightly clustered. The AMD Radeon RX 6400 averages 6001 points, a 0.3% difference from the 760M. The NVIDIA GeForce GTX 770M also averages 6000 points, again a 0.3% delta. The NVIDIA RTX PRO 6000 Blackwell Server averages 5996 points, a 0.4% difference. The NVIDIA Quadro P2000 averages 6049 points, sitting 0.5% above the 760M. This grouping indicates the 760M's recorded performance lands in a narrow band where single-digit percentage shifts separate it from several distinct competitors.

Because the MI300A has no benchmark entries, no win/loss tally can be derived from direct comparisons. The wins counter for each item stands at zero. The comparison necessarily rests on the architectural and specification records rather than measured performance deltas.

Where Each One Wins

The Radeon 760M wins in any scenario where benchmark scores exist, since it is the only one of the two with recorded results. The Passmark DirectX 9 score of 65 leads its own suite, and the Geekbench Vulkan score of 30336 is the highest single number in its record. The Vulkan result is roughly 50% higher than the OpenCL score of 20255, which suggests the architecture's graphics-oriented workload scaling favors the Vulkan API in the recorded data.

The MI300A has no recorded benchmark wins. Its database profile instead shows a compute-oriented design with a 61.29 TFLOPS FP32 rating, a 5.32 TB/s memory bandwidth, and 128 GB of HBM3 memory. These figures indicate a workload profile aimed at data-center scale compute, but the lack of measured scores means no win can be assigned from the benchmark records.

The Radeon 760M's nearest rival deltas all fall within 0.5% in either direction, which puts it in a competitive band rather than a dominant position. Its 0.3% lead over the RX 6400 and GTX 770M, and its 0.4% lead over the RTX PRO 6000 Blackwell Server, are effectively statistical ties. The 0.5% deficit to the Quadro P2000 is similarly marginal.

Architecture Differences

The MI300A uses CDNA 3.0 architecture on a chip called Aqua Vanjaram, built on a 5 nm process at TSMC.

The Verdict

The data supports a clear split by workload class. The AMD Instinct MI300A is a compute accelerator with 128 GB of HBM3 memory, 5.32 TB/s bandwidth, 61.29 TFLOPS FP32, and a 750 W TDP, designed for OAM modules with no display outputs. The AMD Radeon 760M is an integrated GPU with 512 shading units, 8 ray tracing cores, 15 W TDP, and full API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

The 760M is the only one with benchmark results, and those results place it in a tight competitive cluster with the RX 6400, GTX 770M, RTX PRO 6000 Blackwell Server, and Quadro P2000, all within 0.5% of its average score. The MI300A has no measured scores in the database, so no performance verdict can be drawn from benchmark data.

The choice depends entirely on the intended role. The MI300A's specifications point to data-center compute workloads requiring massive memory bandwidth and high FP32 throughput. The 760M's specifications point to integrated graphics duties in a low-power system, with a 2599 MHz boost clock and motherboard-dependent display outputs. The MI300A has no display outputs and no API support for graphics standards, confirming it is not a rendering part. The 760M is the only one of the two that can output to a display at all.

The production status also differs: the 760M is active, while the MI300A has no production status recorded. The MI300A's 50th percentile placement with zero average score reflects missing data, not a measured midpoint. The 760M's 35th percentile with a 6019 average score is a measured position. Users seeking a graphics solution with recorded performance should look to the 760M. Users seeking a high-bandwidth compute accelerator should consider the MI300A based on its specification sheet, with the caveat that no benchmark results exist in the database to confirm its real-world standing.
