AMD Instinct MI300A vs NVIDIA GeForce RTX 4070 Ti Comparison

Where Each One Wins

The AMD Instinct MI300A and NVIDIA GeForce RTX 4070 Ti occupy entirely different corners of the GPU landscape. The data in the database shows zero overlapping benchmark results, which means a direct performance comparison is impossible from recorded measurements. The MI300A has an empty benchmark array, while the RTX 4070 Ti carries ten recorded tests across DirectX, OpenCL, Vulkan, and compute workloads.

The RTX 4070 Ti is the only one of the two with measured scores. Its strongest recorded result comes from Geekbench Vulkan with a score of 213808, followed by Geekbench OpenCL at 176953. The Passmark G3D suite delivers 31624, while Passmark GPU Compute reaches 18396. These numbers place the card at the 84th percentile against all GPUs in the database, with an average benchmark score of 44795. The nearest rivals confirm its positioning: the RTX 5090 Mobile sits 0.8% lower, the Radeon Pro 5500 XT is 1.3% lower, the Intel Arc A730M trails by 1.7%, and the RTX A6000 is 1.6% higher.

The MI300A cannot claim any benchmark wins because no scores exist for it. Its percentile ranking of 50 against all GPUs reflects the absence of recorded testing, not measured performance. The card is built for compute accelerators in OAM module form, with no display outputs and no graphics API support (DirectX, OpenGL, and Vulkan are all listed as N/A). It is not a rendering card at all. The data shows a clear division: the RTX 4070 Ti wins every category where measurements exist, while the MI300A exists outside the consumer benchmark space entirely.

Architecture Differences

The two chips share a 5 nm process node from TSMC, but every other architectural detail diverges sharply. The MI300A uses the CDNA 3.0 architecture on a chip called Aqua Vanjaram. It packs 153,000 million transistors across a 1017 mm² die, yielding a transistor density of 150.4 million per square millimeter. The RTX 4070 Ti uses Ada Lovelace on the AD104 chip, with 35,800 million transistors on a 294 mm² die, for a density of 121.8 million per square millimeter. The MI300A has more than four times the transistor count on more than three times the die area.

Memory systems could not be more different. The MI300A carries 128 GB of HBM3 on an 8192-bit bus, producing 5.32 TB/s of bandwidth. The RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus, with 504.2 GB/s. The MI300A delivers over ten times the memory capacity and over ten times the bandwidth. The RTX 4070 Ti compensates with a much higher memory clock: 1313 MHz base, 21 Gbps effective, versus 1300 MHz and 5.2 Gbps effective on the MI300A. The bus width difference explains why the MI300A still dominates bandwidth despite the lower effective speed.

Compute resources also favor the MI300A on raw counts. It has 14592 shading units and 912 texture mapping units, but zero ROPs, which aligns with its non-rendering purpose. The RTX 4070 Ti has 7680 shading units, 240 TMUs, and 80 ROPs. The MI300A produces 61.29 TFLOPS of FP32 compute and a texture rate of 1,915.2 GTexel/s. The RTX 4070 Ti reaches 40.09 TFLOPS FP32, matches that figure for FP16 at a 1:1 ratio, and delivers a texture rate of 626.4 GTexel/s. The MI300A leads in raw FP32 by roughly 53% and in texture rate by roughly three times, though it has no pixel rate at all (0 MPixel/s) versus 208.8 GPixel/s for the RTX 4070 Ti.

The RTX 4070 Ti includes 60 ray tracing cores and 240 tensor cores, features entirely absent from the MI300A. Clock speeds favor the NVIDIA card: 2310 MHz base and 2610 MHz boost versus 1000 MHz base and 2100 MHz boost on the AMD accelerator. Power draw also differs substantially. The MI300A is rated at 750 W TDP with no power connectors (it uses an OAM module interface) and suggests a 1150 W PSU. The RTX 4070 Ti draws 285 W through a single 16-pin connector and suggests a 600 W PSU.

The Verdict

The recorded data points to two completely different products with no shared use case. The RTX 4070 Ti is a consumer gaming and workstation card with DisplayPort and HDMI outputs, full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. Its benchmark scores place it at the 84th percentile, with an average score of 44795. The MI300A is a server accelerator with no display outputs, no graphics APIs, and no measured benchmarks. Its 50th percentile ranking is a placeholder, not a performance statement.

A user or workload that needs rendering, ray tracing, or graphics APIs should use the RTX 4070 Ti. It has the only recorded scores in this comparison. A workload that needs massive memory capacity, extreme bandwidth, or dense FP32 compute in a server form factor would look to the MI300A, but the database contains no numbers to confirm its real-world performance. The data cannot validate the MI300A as a benchmark leader anywhere because no benchmark exists for it. The RTX 4070 Ti wins the comparison by default, but that win reflects data availability, not architectural superiority.

FAQ

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for this pair. The headToHeadBenchmarks array is empty, and the wins counters show zero for both sides. This absence is itself informative: the two cards never appear in the same test suite.

The RTX 4070 Ti carries all ten recorded benchmark scores. In 3DMark Steel Nomad DX12, it scores 5024. Geekbench OpenCL returns 176953, and Geekbench Vulkan returns 213808. Passmark results are mixed across generations: DirectX 9 scores 352, DirectX 10 scores 187, DirectX 11 scores 288, and DirectX 12 scores 116. Passmark G2D reaches 1200, G3D reaches 31624, and GPU Compute reaches 18396.

The largest recorded wins for the RTX 4070 Ti are in Geekbench Vulkan and OpenCL, where scores exceed 176000 and 213000 respectively. These are synthetic compute tests that exercise general GPU capabilities. The 3DMark Steel Nomad DX12 score of 5024 shows modern rendering performance, while the Passmark G3D score of 31624 confirms sustained graphics throughput. The Passmark DirectX 12 score of 116 is the lowest recorded result, indicating that older API paths may not reflect the card's full capability.

The MI300A has no scores to compare against any of these. Its 61.29 TFLOPS FP32 figure suggests raw compute that would likely outperform the RTX 4070 Ti in compute-heavy workloads, but the database carries no test results to verify that. The texture rate difference, 1,915.2 GTexel/s versus 626.4 GTexel/s, points the same direction, but again without measured benchmarks, it remains a specification, not a result.

The nearest rival data for the RTX 4070 Ti provides context for its standing. The RTX 5090 Mobile scores 45152, which is 0.8% above the RTX 4070 Ti. The Radeon Pro 5500 XT scores 45384, 1.3% above. The RTX A6000 scores 44075, 1.6% below. The Intel Arc A730M scores 45592, 1.7% above. These four rivals bracket the RTX 4070 Ti within a narrow 1.7% range, indicating that its average score of 44795 sits in a tightly clustered competitive field.
