AMD Instinct MI355X vs AMD Radeon RX 9070 GRE Comparison

AMD Instinct MI355X and AMD Radeon RX 9070 GRE are both AMD designs, but they are built for entirely different purposes. The MI355X is a data center compute accelerator built on CDNA 4.0, while the RX 9070 GRE is a client graphics card built on RDNA 4.0. The database contains no overlapping benchmark scores for these two parts, and the MI355X has no recorded benchmark entries at all, with an average benchmark score of zero. The RX 9070 GRE, by contrast, has two recorded entries in the database: a 3DMark Steel Nomad DX12 score of 5,424 and a Geekbench OpenCL score of 109,309, giving it an overall average benchmark score of 57,367 and a percentile rank of 87 among all GPUs. The data indicates that any direct comparison must rely on architectural and specification differences rather than measured performance parity.

Where Each One Wins

The Radeon RX 9070 GRE wins the only measurable performance categories in the database. It has an average benchmark score of 57,367, which places it in the 87th percentile of all GPUs. Its nearest rivals in the database are the Intel Arc A580 (average score 57,756, delta -0.7%), the AMD Radeon RX 5600 OEM (58,085, delta -1.2%), the Intel Arc A570M (58,239, delta -1.5%), and the AMD Radeon RX 6950 XT (58,392, delta -1.8%). These deltas show that the RX 9070 GRE sits within about two percent of these four competing parts in aggregate scoring, slightly behind each of them. The MI355X, in contrast, has no recorded benchmarks, a zero average score, and a 50th percentile rank, which is the database default for parts without measured results.

For graphics output, the RX 9070 GRE is the only one of the two with display connectivity, offering 1x HDMI 2.1b and 3x DisplayPort 2.1a outputs. The MI355X has no display outputs at all. The RX 9070 GRE also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI355X lists N/A for DirectX, OpenGL, and Vulkan. In any client-side rendering or gaming workload, the RX 9070 GRE is the only part with the software API support and display path to function. The MI355X wins on raw compute capacity in several specification categories. It delivers 78.64 TFLOPS FP32 and 78.64 TFLOPS FP16 (1:1), compared to 34.28 TFLOPS FP32 and 34.28 TFLOPS FP16 (1:1) for the RX 9070 GRE. The MI355X texture rate is 2,457.6 GTexel/s versus 535.7 GTexel/s for the RX 9070 GRE. The MI355X also carries 288 GB of HBM3e memory on an 8192-bit bus with 8.19 TB/s of bandwidth, versus 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s for the RX 9070 GRE. The MI355X pixel rate is recorded as 0 MPixel/s, while the RX 9070 GRE has a pixel rate of 267.8 GPixel/s, indicating the MI355X is not designed for rasterization output.

The Verdict

The recorded data shows two fundamentally different products. The Radeon RX 9070 GRE is the only one with any benchmark results, the only one with display outputs, and the only one with a consumer graphics API stack. Its 87th percentile ranking and average score of 57,367 indicate it is a functional client GPU, though its nearest rivals, the Intel Arc A580, RX 5600 OEM, Arc A570M, and RX 6950 XT, all hold slightly higher average scores. The MI355X has no benchmark evidence in the database, no graphics outputs, and no client API support, so it cannot be positioned as a gaming or desktop graphics card based on the available data. The MI355X instead shows its strength in specification-level compute attributes: more than double the FP32 throughput, roughly 4.6 times the texture rate, and 24 times the memory capacity with 19 times the memory bandwidth. For anyone needing a client GPU with measured performance, the RX 9070 GRE is the only supported choice in this comparison. For anyone needing a high-capacity compute accelerator with no display output, the MI355X is the only part in this pair that fits that description.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for the AMD Instinct MI355X versus the AMD Radeon RX 9070 GRE. The MI355X has an empty benchmark array, an average benchmark score of 0, and no nearest rivals listed. The RX 9070 GRE has two recorded benchmark scores. Its 3DMark Steel Nomad DX12 result is 5,424, and its Geekbench OpenCL result is 109,309. The average of those two figures is 57,367. The RX 9070 GRE percentile versus all GPUs is 87. The nearest rival data for the RX 9070 GRE shows the Intel Arc A580 at an average score of 57,756, which is 0.7% higher than the RX 9070 GRE. The AMD Radeon RX 5600 OEM averages 58,085, 1.2% higher. The Intel Arc A570M averages 58,239, 1.5% higher. The AMD Radeon RX 6950 XT averages 58,392, 1.8% higher. These four rivals all sit within 1.8% of the RX 9070 GRE in average score, which means the RX 9070 GRE is competitive with them but marginally behind in each case. The MI355X cannot be placed on this scale because it has no measured data. The FP32 comparison is the clearest compute gap: 78.64 TFLOPS for the MI355X versus 34.28 TFLOPS for the RX 9070 GRE, a 2.29 times difference. The FP16 figures are identical to the FP32 figures for both parts, as both are listed as 1:1. The texture rate gap is 2,457.6 GTexel/s versus 535.7 GTexel/s, a 4.59 times difference. Memory bandwidth shows 8.19 TB/s versus 432.0 GB/s, a difference of roughly 19 times in favor of the MI355X.
