AMD Instinct MI300X vs NVIDIA GeForce RTX 5070 Ti SUPER Comparison

Head-to-Head Benchmarks

The recorded data does not contain any head-to-head benchmark results between the AMD Instinct MI300X and the NVIDIA GeForce RTX 5070 Ti SUPER. The database lists only one benchmark for each part, and they are entirely different test types, which prevents a direct comparison of performance across a common workload.

The AMD Instinct MI300X scores 317994 in Geekbench OpenCL. That result places it in the 100th percentile among all GPUs in the database. The NVIDIA GeForce RTX 5070 Ti SUPER delivers a 3DMark Steel Nomad DX12 score of 6269.5, which lands in the 36th percentile overall. These are not comparable metrics: one is a compute-oriented OpenCL workload, the other is a DirectX 12 gaming benchmark. The percentile gap does indicate that the MI300X sits at the very top of the database distribution, while the RTX 5070 Ti SUPER sits below the median.

The nearest rivals for the MI300X are all data center accelerators. The NVIDIA H200 NVL leads with an average score of 334891, which is 5% higher than the MI300X. The NVIDIA B200 reaches 345482, an 8% advantage. On the other side, the NVIDIA L40S trails by 7.5% (295763), and the NVIDIA RTX 6000 Ada Generation sits 10.7% behind at 287237. The MI300X is therefore bracketed by the H200 and B200 above it and the L40S and RTX 6000 Ada below it, with all deltas within a roughly 19-point percentage span.

The RTX 5070 Ti SUPER has a much tighter rival cluster. The NVIDIA GeForce RTX 4070 Ti SUPER AD102 scores 6270, exactly matching the RTX 5070 Ti SUPER with a 0% delta. The AMD FirePro W600 trails by 0.8% at 6223, while the NVIDIA Quadro K620 sits 0.2% behind at 6282, and the AMD Radeon R7 M350 is 0.9% ahead at 6327. These four rivals are all within one percentage point of the RTX 5070 Ti SUPER, indicating that the 3DMark result places it in an extremely crowded performance band.

Because the head-to-head benchmark array is empty, the database does not offer a single workload where both products were measured. Any comparison of their relative speed must rely on architectural specifications and the context of their respective benchmark categories rather than a shared test result.

Architecture Differences

The two products come from fundamentally different design lineages. The AMD Instinct MI300X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, part of the Instinct (MIx) generation. The NVIDIA GeForce RTX 5070 Ti SUPER uses the GB203 chip on Blackwell 2.0 architecture, part of the GeForce 50 series. Both are fabricated by TSMC on a 5 nm process, but the transistor counts diverge sharply. The MI300X packs 153,000 million transistors across a 1017 mm² die, giving a transistor density of 150.4 million per mm². The RTX 5070 Ti SUPER contains 45,600 million transistors on a 378 mm² die, for a density of 120.6 million per mm². The MI300X die is nearly three times larger in area and holds more than three times the transistor count.

Memory is another major separation point. The MI300X ships with 192 GB of HBM3 on an 8192-bit bus, producing 5.32 TB/s of bandwidth. The RTX 5070 Ti SUPER uses 16 GB of GDDR7 on a 256-bit bus, yielding 896.0 GB/s. The MI300X has 12 times the capacity and roughly 5.9 times the bandwidth. The memory clocks reflect the different technologies: the MI300X runs at 1300 MHz with 5.2 Gbps effective, while the RTX 5070 Ti SUPER runs at 1750 MHz with 28 Gbps effective. The bus width difference is the dominant factor in bandwidth.

Compute resources also differ in scale. The MI300X has 19456 shading units, 1216 TMUs, and no ROPs, with a pixel rate of 0 MPixel/s and a texture rate of 2553.6 GTexel/s. The RTX 5070 Ti SUPER has 8960 shading units, 280 TMUs, and 96 ROPs, with a pixel rate of 235.4 GPixel/s and a texture rate of 686.6 GTexel/s. Floating point throughput tells a similar story: the MI300X reaches 81.72 TFLOPS for both FP32 and FP16, while the RTX 5070 Ti SUPER reaches 43.94 TFLOPS for both. The MI300X delivers 1.86 times the FP32 throughput of the RTX 5070 Ti SUPER.

Clock speeds favor the NVIDIA part heavily. The RTX 5070 Ti SUPER has a base clock of 2295 MHz and a boost clock of 2452 MHz, versus 1000 MHz base and 2100 MHz boost for the MI300X. The MI300X compensates with massive parallelism and memory bandwidth. The RTX 5070 Ti SUPER includes 70 ray tracing cores and 280 tensor cores, while the MI300X lists none for either. The MI300X has no display outputs, while the RTX 5070 Ti SUPER provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. API support also diverges: the RTX 5070 Ti SUPER supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300X lists N/A for all three.

Power and physical design differ accordingly. The MI300X is rated at 750 W TDP with no power connectors (OAM Module form factor) and a suggested PSU of 1150 W. The RTX 5070 Ti SUPER is rated at 350 W TDP, uses a dual-slot design with a single 16-pin connector, and measures 304 mm by 137 mm by 48 mm. The MI300X has no listed dimensions.

The Verdict

The data points to two entirely different use cases. The AMD Instinct MI300X is a data center accelerator with 192 GB of HBM3, 5.32 TB/s of bandwidth, 81.72 TFLOPS of FP32, and a 100th percentile Geekbench OpenCL score. Its nearest rivals are the NVIDIA H200 NVL, B200, L40S, and RTX 6000 Ada Generation, all of which are server-class accelerators. The MI300X slots between the H200 and B200 (which are 5% and 8% ahead) and the L40S and RTX 6000 Ada (which are 7.5% and 10.7% behind).

The NVIDIA GeForce RTX 5070 Ti SUPER is a consumer graphics card with 16 GB of GDDR7, 896.0 GB/s of bandwidth, 43.94 TFLOPS of FP32, 70 ray tracing cores, 280 tensor cores, and direct display outputs. Its 3DMark Steel Nomad DX12 score of 6269.5 sits in the 36th percentile and is within one percentage point of four different rivals, including an exact match with the RTX 4070 Ti SUPER AD102.

The MI300X wins outright on memory capacity, memory bandwidth, shading units, FP32 throughput, texture rate, and transistor count. The RTX 5070 Ti SUPER wins on clock speed, ROPs, ray tracing cores, tensor cores, pixel rate, API support, display outputs, and power efficiency (350 W versus 750 W). The launch MSRP of the RTX 5070 Ti SUPER is 749 USD.

For a workload dominated by large memory footprints and raw compute throughput, the MI300X is the clear choice. For a workload requiring rasterization, ray tracing, display output, or consumer API compatibility, the RTX 5070 Ti SUPER is the only one of the two that can function at all. The absence of a common benchmark prevents any claim of overall superiority; the database simply supports a division by workload type.

Where Each One Wins

The AMD Instinct MI300X wins in every memory-centric metric. Its 192 GB capacity and 5.32 TB/s bandwidth are unmatched by the RTX 5070 Ti SUPER's 16 GB and 896.0 GB/s. For models or datasets that exceed 16 GB, the MI300X is the only viable option. Its 81.72 TFLOPS FP32 and FP16 throughput are 1.86 times the RTX 5070 Ti SUPER's 43.94 TFLOPS. The 19456 shading units and 1216 TMUs provide a texture rate of 2553.6 GTexel/s, nearly four times the RTX 5070 Ti SUPER's 686.6 GTexel/s. The MI300X also wins on transistor count (153,000 million versus 45,600 million) and die size (1017 mm² versus 378 mm²). Its 100th percentile Geekbench OpenCL ranking places it at the top of the database distribution for that workload.

The NVIDIA GeForce RTX 5070 Ti SUPER wins on clock speed, with a 2295 MHz base and 2452 MHz boost versus the MI300X's 1000 MHz base and 2100 MHz boost. It has 96 ROPs and a pixel rate of 235.4 GPixel/s, while the MI300X has zero ROPs and a pixel rate of 0 MPixel/s. The RTX 5070 Ti SUPER includes 70 ray tracing cores and 280 tensor cores, features absent from the MI300X. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300X lists N/A for all APIs. The RTX 5070 Ti SUPER provides 1x HDMI 2.1b and 3x DisplayPort 2.1b, whereas the MI300X has no display outputs. Its 350 W TDP is less than half the MI300X's 750 W TDP, and its dual-slot design with a 16-pin connector is far more conventional than the OAM module format.

The workload split is clear. The MI300X wins for large-scale compute, memory-bound workloads, and data center deployment. The RTX 5070 Ti SUPER wins for any task requiring graphics output, ray tracing, tensor acceleration, or consumer API support. The database records no shared benchmark, so the division rests on architecture and specifications rather than a measured head-to-head result.
