AMD Instinct MI300A vs NVIDIA GeForce RTX 5070 Ti SUPER Comparison

AMD Instinct MI300A and NVIDIA GeForce RTX 5070 Ti SUPER occupy opposite ends of the hardware spectrum, one designed for massive compute workloads and the other for client graphics. The recorded data shows a clear split in capabilities, with the MI300A focusing on raw throughput and memory capacity, while the RTX 5070 Ti SUPER delivers a complete feature set for display and rendering tasks. Benchmark results indicate that neither part directly competes with the other in typical use cases, but the specifications reveal distinct strengths that matter for specific workloads.

Where Each One Wins

The AMD Instinct MI300A wins decisively in compute density and memory capacity. It uses an 8192-bit memory bus with 128 GB of HBM3, delivering 5.32 TB/s of bandwidth. That is more than five times the memory capacity and nearly six times the bandwidth of the RTX 5070 Ti SUPER. For workloads that need massive datasets resident on the GPU, such as large language model inference or scientific simulations, the MI300A is the clear choice. Its FP32 throughput of 61.29 TFLOPS also exceeds the RTX 5070 Ti SUPER's 43.94 TFLOPS, giving it a 39.5% advantage in single-precision compute.

The NVIDIA GeForce RTX 5070 Ti SUPER wins in every area related to graphics output and consumer features. It has 70 RT cores and 280 tensor cores, enabling hardware-accelerated ray tracing and AI processing. It also has 96 ROPs, allowing it to output 235.4 GPixel/s, while the MI300A has 0 ROPs and a pixel rate of 0 MPixel/s because it has no display outputs. The RTX 5070 Ti SUPER supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI300A reports N/A for all graphics APIs. The NVIDIA part also includes display outputs: one HDMI 2.1b and three DisplayPort 2.1b ports, whereas the MI300A has no outputs at all.

The RTX 5070 Ti SUPER also wins on clock speeds and efficiency per watt. Its base clock of 2295 MHz and boost clock of 2452 MHz are substantially higher than the MI300A's 1000 MHz base and 2100 MHz boost. The NVIDIA part consumes 350 W, while the MI300A draws 750 W, meaning the RTX 5070 Ti SUPER delivers its performance at less than half the power draw. The data shows a significant advantage for the consumer card in power efficiency.

Architecture Differences

The two processors use fundamentally different architectures built for different purposes. The AMD Instinct MI300A uses CDNA 3.0 architecture on the Aqua Vanjaram chip, manufactured on a 5 nm process at TSMC. It contains 153,000 million transistors on a 1017 mm² die, resulting in a transistor density of 150.4 million per mm². The chip has 14,592 shading units and 912 TMUs but no ROPs, no RT cores, and no tensor cores listed in the database. This configuration prioritizes raw compute throughput over graphics rendering.

The NVIDIA GeForce RTX 5070 Ti SUPER uses Blackwell 2.0 architecture on the GB203 chip, also manufactured on a 5 nm process at TSMC. It contains 45,600 million transistors on a 378 mm² die, giving it a transistor density of 120.6 million per mm². The chip has 8,960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. This is a fully featured graphics processor with dedicated hardware for ray tracing, AI workloads, and rasterization.

The memory subsystems reflect the different design goals. The MI300A uses HBM3 with a 8192-bit bus, while the RTX 5070 Ti SUPER uses GDDR7 with a 256-bit bus. The MI300A's memory clock runs at 1300 MHz with 5.2 Gbps effective speed, while the RTX 5070 Ti SUPER runs at 1750 MHz with 28 Gbps effective speed. The MI300A's much wider bus compensates for its lower per-pin speed, resulting in far higher aggregate bandwidth.

Power delivery also differs. The MI300A is an OAM module with no power connectors listed and requires a suggested PSU of 1150 W. The RTX 5070 Ti SUPER is a dual-slot card with a single 16-pin power connector. The MI300A's 750 W TDP is more than double the RTX 5070 Ti SUPER's 350 W TDP.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Instinct MI300A and the NVIDIA GeForce RTX 5070 Ti SUPER. The MI300A has no recorded benchmark scores, an average benchmark score of 0, and no nearest rivals listed. Its percentile rank among all GPUs is 50, but this appears to be a neutral placeholder given the absence of measured results.

The RTX 5070 Ti SUPER has one recorded benchmark result: a 3DMark Steel Nomad DX12 score of 6269.5, with an average benchmark score of 6270. This places it at the 36th percentile among all GPUs. The nearest rivals for this score are the NVIDIA GeForce RTX 4070 Ti SUPER AD102 with an identical average score of 6270 and a delta of 0%, the NVIDIA Quadro K620 with a score of 6282 (0.2% higher), the AMD FirePro W600 with a score of 6223 (0.8% lower), and the AMD Radeon R7 M350 with a score of 6327 (0.9% higher).

The recorded data shows that the RTX 5070 Ti SUPER's benchmark score sits within a tight cluster of results, with all nearest rivals within 1% of each other. The 36th percentile ranking indicates that 64% of all GPUs in the database score higher in this particular DX12 test. This metric primarily reflects graphics rendering performance, which is not applicable to the MI300A given its lack of graphics APIs and display outputs.

FAQ

Q: Does the AMD Instinct MI300A support ray tracing?

A: No. The MI300A has no RT cores listed in the database and reports N/A for DirectX, OpenGL, and Vulkan support. It also has no display outputs, making it unsuitable for any graphics rendering workload.

The Verdict

The data supports a clear separation of use cases based on the recorded specifications. The AMD Instinct MI300A is built for compute-intensive tasks that benefit from massive memory capacity and raw FP32 throughput. Its 128 GB HBM3 pool and 5.32 TB/s bandwidth make it suitable for workloads that require large datasets to remain on the GPU, while its 61.29 TFLOPS FP32 output and 1,915.2 GTexel/s texture rate indicate strong general compute capability. However, its lack of display outputs, graphics APIs, and RT or tensor cores means it cannot function as a conventional graphics card.

The NVIDIA GeForce RTX 5070 Ti SUPER is the opposite: a fully featured consumer graphics card with 70 RT cores, 280 tensor cores, 96 ROPs, and support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 235.4 GPixel/s pixel rate and 686.6 GTexel/s texture rate, combined with a 3DMark Steel Nomad score of 6269.5, confirm its graphics rendering capability. Its 16 GB of GDDR7 memory and 896.0 GB/s bandwidth are sufficient for consumer gaming and content creation, though they are far below the MI300A's capacity.

The power and physical characteristics reinforce the split. The MI300A is an OAM module with 750 W TDP and no power connectors, intended for server installations with a robust power delivery system. The RTX 5070 Ti SUPER is a dual-slot card with a single 16-pin connector and 350 W TDP, suitable for standard desktop systems. The RTX 5070 Ti SUPER also has defined physical dimensions of 304 mm length, 137 mm height, and 48 mm width, while the MI300A has no listed dimensions.

Users who need a graphics card for gaming, rendering, or workstation use should select the RTX 5070 Ti SUPER, as it is the only option with display outputs and graphics API support. Users who need a compute accelerator for large-scale data processing should select the MI300A, as its memory capacity and bandwidth exceed anything the NVIDIA card can offer. The two parts do not overlap in functionality, and the choice depends entirely on the workload.
