AMD Instinct MI300 vs AMD Radeon RX 9070 GRE Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Instinct MI300 and the AMD Radeon RX 9070 GRE. The Instinct MI300 has no recorded benchmark scores, no average benchmark score, and no nearest rival entries. Its percentile rank among all GPUs is 50. The Radeon RX 9070 GRE, by contrast, has two recorded benchmark scores: 5,424 in 3DMark Steel Nomad DX12 and 109,309 in Geekbench OpenCL. Its average benchmark score is 57,367, and its percentile rank is 87. Because the MI300 lacks any benchmark data, a direct numerical comparison of measured performance cannot be constructed from the database. The only comparable figures available are the percentile ranks, which place the MI300 at the median of all GPUs and the RX 9070 GRE well above it.

The RX 9070 GRE's average score of 57,367 places it narrowly ahead of four nearest rivals. It sits 0.7% above the Intel Arc A580, which averages 57,756, meaning the RX 9070 GRE trails that card by a hair. Against the AMD Radeon RX 5600 OEM, the RX 9070 GRE is 1.2% lower, and against the Intel Arc A570M it is 1.5% lower. The largest gap in the rival set is with the AMD Radeon RX 6950 XT, where the RX 9070 GRE is 1.8% behind. These deltas are all negative, which indicates that the RX 9070 GRE's average score is slightly below each listed rival. The differences are small, all within a 2.5% band, so the recorded data shows a cluster of similar-performing cards rather than a clear leader.

The Instinct MI300's zero benchmark score and 50th percentile stand in contrast. Without recorded measurements, the database treats it as an unranked product in terms of actual tested performance. The RX 9070 GRE's 87th percentile reflects a position well above the midpoint, but the margin cannot be quantified because the MI300 has no score to compare. The data simply does not support a numeric head-to-head statement.

Where Each One Wins

The Radeon RX 9070 GRE wins in every category where recorded data exists. It has benchmark scores, an average score, a percentile rank, and a production status of Active. The Instinct MI300 has none of those. The RX 9070 GRE also has a full set of display outputs: 1x HDMI 2.1b and 3x DisplayPort 2.1a. The MI300 lists no display outputs at all. For any workload that requires a monitor output, the RX 9070 GRE is the only option in this comparison.

The RX 9070 GRE supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300 lists N/A for DirectX, OpenGL, and Vulkan. Any application relying on those graphics APIs can only run on the RX 9070 GRE. The MI300's architecture targets compute workloads without graphics API support, so it cannot be used for standard gaming or consumer graphics applications.

The MI300 wins in raw compute resource counts. It uses 14,080 shading units, 880 texture mapping units, and has a texture rate of 1,496.0 GTexel/s. The RX 9070 GRE uses 3,072 shading units, 192 TMUs, and has a texture rate of 535.7 GTexel/s. The MI300's FP32 throughput is 47.87 TFLOPS, and its FP16 throughput is also 47.87 TFLOPS (1:1). The RX 9070 GRE delivers 34.28 TFLOPS in both FP32 and FP16 (1:1). The MI300 also has 128 GB of HBM3 memory on an 8192-bit bus with 5.32 TB/s bandwidth. The RX 9070 GRE has 12 GB of GDDR6 on a 192-bit bus with 432.0 GB/s bandwidth. These differences point to the MI300 as the stronger choice for memory-bound compute tasks.

Architecture Differences

The Instinct MI300 uses the CDNA 3.0 architecture on the Aqua Vanjaram chip. The Radeon RX 9070 GRE uses RDNA 4.0 on the Navi 48 chip. The MI300 is built on a 5 nm process at TSMC, while the RX 9070 GRE uses a 4 nm process, also at TSMC. The MI300 contains 153,000 million transistors on a 1017 mm² die, giving a transistor density of 150.4 million per mm². The RX 9070 GRE contains 53,900 million transistors on a 357 mm² die, with a density of 151.0 million per mm². The density figures are nearly identical, but the MI300's die is roughly three times larger and carries nearly three times the transistor count.

The MI300 has no ROPs and a pixel rate of 0 MPixel/s. The RX 9070 GRE has 96 ROPs and a pixel rate of 267.8 GPixel/s. The MI300 has no RT cores listed, while the RX 9070 GRE has 48 RT cores. The MI300 lists no tensor cores, and neither does the RX 9070 GRE. The MI300's clock behavior differs sharply: a base clock of 1000 MHz and a boost of 1700 MHz, with memory at 1300 MHz (5.2 Gbps effective). The RX 9070 GRE runs a base clock of 1420 MHz, a game clock of 2220 MHz, a boost of 2790 MHz, and memory at 2250 MHz (18 Gbps effective). The RX 9070 GRE is clocked much higher in every frequency domain.

The MI300 draws 600 W and requires a 1000 W suggested PSU. The RX 9070 GRE draws 220 W and suggests a 550 W PSU. Both use 2x 8-pin power connectors. The MI300 is a dual-slot card measuring 267 mm in length and 111 mm in height. The RX 9070 GRE is also dual-slot, but its dimensions are not recorded. The MI300 uses PCIe 5.0 x16, as does the RX 9070 GRE. The MI300's release date is January 3, 2023, and its predecessor is Radeon Instinct. The RX 9070 GRE's release date is May 7, 2025, and its predecessor is Navi III.

The Verdict

The data supports a clear split. The Radeon RX 9070 GRE is the only one of the two with recorded benchmark results, a percentile rank of 87, and support for graphics APIs and display outputs. It is the choice for any workload that needs DirectX 12 Ultimate, Vulkan 1.4, OpenGL 4.6, or a physical display connection. Its 12 GB of GDDR6 memory and 432.0 GB/s bandwidth are modest, but its 96 ROPs and 48 RT cores give it rasterization and ray tracing capabilities that the MI300 does not list. Its 220 W TDP and 550 W suggested PSU also make it far easier to integrate into a standard system.

The Instinct MI300 is the choice for compute-heavy tasks that do not require graphics output. Its 128 GB of HBM3 memory, 8192-bit bus, and 5.32 TB/s bandwidth are in a different class from the RX 9070 GRE's 12 GB GDDR6. Its 14,080 shading units and 1,496.0 GTexel/s texture rate dwarf the RX 9070 GRE's 3,072 shading units and 535.7 GTexel/s. Its FP32 and FP16 throughput of 47.87 TFLOPS exceeds the RX 9070 GRE's 34.28 TFLOPS. The MI300 also has no launch MSRP recorded, while the RX 9070 GRE has a launch MSRP of 549 USD.

Users who need a tested, active graphics card with modern API support should select the RX 9070 GRE. Users who need maximum memory capacity and raw compute throughput in a server or accelerator context should consider the MI300, despite its lack of benchmark data. The database records no direct comparison, so the verdict rests on the architectural and feature differences that are documented.
