AMD Instinct MI300X vs NVIDIA GeForce RTX 5070 Comparison

Head-to-Head Benchmarks

The recorded data includes a single direct comparison between the AMD Instinct MI300X and the NVIDIA GeForce RTX 5070. In the Geekbench OpenCL test, the AMD Instinct MI300X delivers a score of 317,994, while the NVIDIA GeForce RTX 5070 records 172,660. The AMD part wins this head-to-head matchup with a delta of 84.2 percent. That margin is substantial, indicating the MI300X is roughly 1.84 times faster in this compute-oriented workload. The RTX 5070, however, has a broader benchmark portfolio in the database. Its average benchmark score across all recorded tests is 40,377, which places it in the 82nd percentile of all GPUs tracked. The MI300X, by contrast, holds a 100th percentile ranking, meaning it sits at the very top of the database's performance distribution, though only one benchmark score (317,994) is recorded for it.

Context from the nearest rivals clarifies the magnitude of the MI300X's OpenCL result. The NVIDIA H200 NVL averages 334,891, which is 5 percent higher than the MI300X's score. The NVIDIA B200 averages 345,482, an 8 percent advantage over the MI300X. On the other side, the NVIDIA L40S averages 295,763, which is 7.5 percent lower than the MI300X, and the NVIDIA RTX 6000 Ada Generation averages 287,237, a 10.7 percent deficit. These deltas show that the MI300X competes in the upper tier of accelerator-class hardware, sitting between the L40S and the H200/B200 pair. For the RTX 5070, its nearest rivals are all far lower in average score. The AMD Radeon Pro 580 averages 40,318, a 0.1 percent difference from the RTX 5070's 40,377. The AMD Radeon Pro WX 7100 averages 40,063, 0.8 percent lower. The AMD Radeon Pro 5300 averages 40,870, which is 1.2 percent higher than the RTX 5070. The NVIDIA RTX A500 Mobile averages 39,568, 2 percent below. These close margins indicate that in its own benchmark set, the RTX 5070 is a mid-pack performer, not an outlier.

The single head-to-head result is heavily lopsided, but it reflects different design goals. The MI300X is built for raw compute throughput, while the RTX 5070 appears optimized for a different mix of workloads. In the OpenCL test, the MI300X's advantage is clear and unambiguous. No other common benchmark exists in the database for these two products, so the comparison rests on this one data point. The RTX 5070 does have a 3DMark Steel Nomad DX12 score of 5,077, but no equivalent score exists for the MI300X, which lacks any recorded 3DMark results. Similarly, the RTX 5070 has multiple Passmark scores (directx_9 at 320, directx_10 at 180, directx_11 at 277, directx_12 at 108, g2d at 1,305, g3d at 29,137, gpu_compute at 15,787) and a Geekbench Vulkan score of 178,923, but the MI300X has none of those entries. Thus, the database offers a narrow but decisive comparison in the compute domain.

Architecture Differences

The AMD Instinct MI300X uses the Aqua Vanjaram chip with a CDNA 3.0 architecture, part of the Instinct (MIx) generation. The NVIDIA GeForce RTX 5070 uses the GB205 chip with a Blackwell 2.0 architecture, part of the GeForce 50-series. Both are fabricated on a 5 nm process at TSMC, but the transistor counts diverge sharply. The MI300X integrates 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per mm². The RTX 5070 has 31,100 million transistors on a 263 mm² die, with a density of 118.3 million per mm². The MI300X's die is roughly 3.9 times larger in area and holds about 4.9 times more transistors, reflecting a design aimed at massive parallel compute rather than consumer graphics efficiency.

Compute resources also differ. The MI300X has 19,456 shading units and 1,216 texture mapping units, but zero ROPs and a pixel rate of 0 MPixel/s. It has no recorded ray tracing cores or tensor cores. The RTX 5070 has 6,144 shading units, 192 TMUs, 80 ROPs, 48 ray tracing cores, and 192 tensor cores. Its pixel rate is 201.0 GPixel/s and texture rate is 482.3 GTexel/s. The MI300X's texture rate is 2,553.6 GTexel/s, more than five times the RTX 5070's figure. In floating-point throughput, the MI300X delivers 81.72 TFLOPS for both FP32 and FP16 (1:1). The RTX 5070 delivers 30.87 TFLOPS for both FP32 and FP16 (1:1). The MI300X is 2.65 times higher in raw FP32 compute.

Memory configurations are fundamentally different. The MI300X uses 192 GB of HBM3 on an 8192-bit bus, providing 5.32 TB/s of bandwidth. The RTX 5070 uses 12 GB of GDDR7 on a 192-bit bus, providing 672.0 GB/s. The MI300X's memory bandwidth is roughly 7.9 times higher, and its capacity is 16 times larger. Clock speeds also differ: the MI300X has a base clock of 1000 MHz and boost of 2100 MHz, with memory at 1300 MHz (5.2 Gbps effective). The RTX 5070 has a base clock of 2325 MHz and boost of 2512 MHz, with memory at 1750 MHz (28 Gbps effective). The RTX 5070 runs at higher clock speeds, but the MI300X compensates with far wider parallel resources.

Board design and interface reflect their separate markets. The MI300X is an OAM module with no power connectors and no display outputs, relying on a PCIe 5.0 x16 bus. It has a TDP of 750 W and a suggested PSU of 1150 W. The RTX 5070 is a dual-slot card measuring 245 mm in length, 115 mm in height, and 40 mm in width. It uses a single 16-pin power connector, has a TDP of 250 W, and a suggested PSU of 600 W. It outputs video through 1x HDMI 2.1b and 3x DisplayPort 2.1b. The MI300X has no API support for DirectX, OpenGL, or Vulkan, while the RTX 5070 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates two products with almost no overlap in intended use. The AMD Instinct MI300X is a compute accelerator with a 100th percentile ranking and an OpenCL score of 317,994, placing it above the NVIDIA L40S and RTX 6000 Ada Generation, and only slightly below the H200 NVL and B200. Its 192 GB HBM3 memory, 5.32 TB/s bandwidth, and 81.72 TFLOPS FP32 make it suited for large-scale compute workloads. The NVIDIA GeForce RTX 5070 is a consumer graphics card with an 82nd percentile ranking, a Vulkan score of 178,923, and a 3DMark Steel Nomad DX12 score of 5,077. Its nearest rivals in average score are all within 2 percent, indicating a mid-range position among its peers.

For a buyer choosing based on the recorded benchmarks, the MI300X is the clear winner in raw compute performance. The 84.2 percent OpenCL lead is decisive. However, the RTX 5070 offers features the MI300X lacks entirely: display outputs, ray tracing cores, tensor cores, DirectX 12 Ultimate support, and a 250 W TDP with a dual-slot form factor. The MI300X has no display outputs, no graphics API support, and draws 750 W. The RTX 5070, with a launch MSRP of 549 USD, is a consumer product with a smaller footprint and lower power demand. The MI300X has no recorded launch MSRP.

The verdict from the data is straightforward. For compute-heavy workloads where the Geekbench OpenCL score is representative, the MI300X is the superior part by a wide margin. For graphics, gaming, or any workload requiring display output or standard graphics APIs, the RTX 5070 is the only viable option between the two. The MI300X's zero ROPs and 0 MPixel/s pixel rate confirm it is not designed for rasterization. The RTX 5070's 80 ROPs and 201.0 GPixel/s pixel rate show it handles conventional graphics rendering. Neither product outperforms the other in a domain it does not target. The database simply records one shared metric, and that metric belongs to the MI300X.
