AMD Instinct MI300X vs NVIDIA GeForce RTX 4070 SUPER Comparison

Head-to-Head Benchmarks

The database contains a single directly comparable benchmark between these two accelerators: Geekbench OpenCL. In that test, the AMD Instinct MI300X records a score of 317,994 against 172,795 for the NVIDIA GeForce RTX 4070 SUPER. That is an 84% advantage for the AMD part. This is the only head-to-head measurement available, so the comparison rests heavily on this result and on each card's broader benchmark profile.

The MI300X sits at the 100th percentile of all GPUs in the database, meaning it outperforms every other recorded GPU in aggregate scoring. Its average benchmark score is 317,994. The RTX 4070 SUPER, by contrast, sits at the 83rd percentile with an average score of 43,223. The gap in average scores is substantial, but the RTX 4070 SUPER has a much wider benchmark portfolio: it records results across DirectX 9, 10, 11, 12, Vulkan, compute, and 2D tests, while the MI300X has only the single OpenCL entry.

Looking at the RTX 4070 SUPER's best results, the PassMark G3D score of 29,995 and the Geekbench Vulkan score of 205,624 show strong graphics throughput. Its PassMark GPU compute score of 17,108 is far below the MI300X's OpenCL number, but the two are not directly comparable due to different test suites. The 3DMark Steel Nomad DX12 score of 4,627 indicates a capable modern DirectX 12 part, a workload category where the MI300X has no recorded data at all, its API support listed as N/A for DirectX, OpenGL, and Vulkan.

In terms of nearest rivals, the MI300X leads the NVIDIA RTX 6000 Ada Generation by 10.7% and the NVIDIA L40S by 7.5%, while trailing the NVIDIA H200 NVL by 5% and the NVIDIA B200 by 8%. The RTX 4070 SUPER's nearest rivals are much closer: it is essentially tied with the Quadro M6000 24 GB at -0.1%, the RTX 5050 Mobile at -0.1%, and the Quadro M6000 at -0.2%, while trailing the RTX 4090 Mobile by only 1%. This contrast shows the MI300X competing in a performance tier where small percentage gaps separate the top data center accelerators, while the RTX 4070 SUPER sits in a dense cluster of consumer and mobile parts.

Architecture Differences

The MI300X uses AMD's CDNA 3.0 architecture on the Aqua Vanjaram chip, built on a 5 nm process at TSMC. It packs 153,000 million transistors across a 1017 mm² die, giving a transistor density of 150.4 million per mm². The RTX 4070 SUPER uses NVIDIA's Ada Lovelace architecture on the AD104 chip, also on a 5 nm TSMC process, but with 35,800 million transistors on a 294 mm² die, a density of 121.8 million per mm². The MI300X thus carries more than four times the transistor count and more than three times the die area.

Memory is the most dramatic differentiator. The MI300X offers 192 GB of HBM3 on an 8192-bit bus with 5.32 TB/s of bandwidth. The RTX 4070 SUPER has 12 GB of GDDR6X on a 192-bit bus with 504.2 GB/s of bandwidth. The AMD part delivers more than ten times the memory capacity and bandwidth. The memory clock on the MI300X is listed at 1300 MHz with 5.2 Gbps effective, while the RTX 4070 SUPER runs at 1313 MHz with 21 Gbps effective.

Compute resources also differ sharply. The MI300X has 19,456 shading units and 1,216 TMUs, but no ROPs, reporting a pixel rate of 0 MPixel/s. The RTX 4070 SUPER has 7,168 shading units, 224 TMUs, and 80 ROPs, with a pixel rate of 198.0 GPixel/s. Texture rates are 2,553.6 GTexel/s for the MI300X versus 554.4 GTexel/s for the RTX 4070 SUPER. FP32 compute is 81.72 TFLOPS for the AMD card, with FP16 at the same 81.72 TFLOPS on a 1:1 basis. The NVIDIA card delivers 35.48 TFLOPS for both FP32 and FP16.

The RTX 4070 SUPER includes 56 ray tracing cores and 224 tensor cores, features the MI300X does not list. It also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI300X reports N/A for all of these APIs. The NVIDIA card has display outputs (1x HDMI 2.1 and 3x DisplayPort 1.4a), whereas the MI300X has no display outputs, reflecting its role as an accelerator module rather than a graphics card.

Clock speeds favor the NVIDIA part. The RTX 4070 SUPER has a base clock of 1980 MHz and a boost of 2475 MHz, compared to 1000 MHz base and 2100 MHz boost on the MI300X. Power figures also diverge: the MI300X has a TDP of 750 W and suggests a 1150 W PSU, while the RTX 4070 SUPER has a 220 W TDP and suggests a 550 W PSU. The MI300X uses an OAM module slot width with no power connectors listed, while the RTX 4070 SUPER is dual-slot with a single 16-pin connector. The bus interfaces are PCIe 5.0 x16 for the AMD part and PCIe 4.0 x16 for the NVIDIA part.

The RTX 4070 SUPER measures 267 mm in length, 112 mm in height, and 42 mm in width. Its production status is marked end-of-life, with the GeForce 50 series listed as its successor. The MI300X was released on 2023-12-05, while the RTX 4070 SUPER followed on 2024-01-16. The RTX 4070 SUPER has a launch MSRP of 599 USD. The MI300X has no launch MSRP recorded in the database.

The Verdict

The recorded data shows two devices built for different purposes. The AMD Instinct MI300X is a data center accelerator with an 84% OpenCL lead over the RTX 4070 SUPER, 192 GB of HBM3 memory, and 81.72 TFLOPS of FP32 compute. It sits at the 100th percentile of all GPUs and beats the RTX 6000 Ada Generation by 10.7% and the L40S by 7.5% in average score. Any workload that can use its OpenCL compute and massive memory footprint will favor the MI300X decisively.

The NVIDIA GeForce RTX 4070 SUPER is a consumer graphics card with display outputs, ray tracing cores, tensor cores, and full DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. It delivers 35.48 TFLOPS of FP32 compute, 198.0 GPixel/s pixel rate, and 554.4 GTexel/s texture rate. Its 220 W TDP and dual-slot design make it suitable for conventional desktop systems, whereas the MI300X requires an OAM module slot and a 1150 W suggested PSU.

The MI300X has no recorded graphics API support and no display outputs, which makes it unsuitable for gaming or any rasterization workload. The RTX 4070 SUPER, despite its lower raw compute, supports the full modern graphics stack. The data indicates the MI300X wins on raw compute and memory capacity, while the RTX 4070 SUPER wins on graphics features, API compatibility, and practical desktop deployment. The choice depends entirely on whether the workload is compute-oriented or graphics-oriented.

Where Each One Wins

The MI300X wins in every measured compute benchmark category. Its OpenCL score of 317,994 places it at the 100th percentile, ahead of the RTX 6000 Ada Generation by 10.7% and the L40S by 7.5%. Its FP32 and FP16 throughput of 81.72 TFLOPS is more than double the RTX 4070 SUPER's 35.48 TFLOPS. Texture rate of 2,553.6 GTexel/s is 4.6 times the RTX 4070 SUPER's 554.4 GTexel/s. Memory bandwidth of 5.32 TB/s is more than ten times the 504.2 GB/s available on the NVIDIA card. The 192 GB capacity dwarfs the 12 GB on the RTX 4070 SUPER, which matters for large models and datasets.

The RTX 4070 SUPER wins in graphics-specific capabilities. It has 80 ROPs and a pixel rate of 198.0 GPixel/s, while the MI300X reports 0 ROPs and 0 MPixel/s. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, whereas the MI300X has no recorded API support. It includes 56 ray tracing cores and 224 tensor cores, features absent from the MI300X's specifications. It has display outputs, a dual-slot form factor, and a 220 W TDP, making it deployable in standard desktop systems. The MI300X requires an OAM module slot, has no display outputs, and draws 750 W.

The RTX 4070 SUPER also has a richer benchmark portfolio, with results across 3DMark Steel Nomad DX12, Geekbench Vulkan, and multiple PassMark tests. Its PassMark G3D score of 29,995 and Vulkan score of 205,624 indicate strong graphics performance in real-world rendering APIs. The MI300X has only the single OpenCL result, so its graphics performance cannot be assessed from the database. For any workload requiring rasterization, ray tracing, or display output, the RTX 4070 SUPER is the only viable option in this comparison. For pure compute throughput and memory capacity, the MI300X dominates.
