AMD Instinct MI300A vs AMD Radeon RX 9070 GRE Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries between the AMD Instinct MI300A and the AMD Radeon RX 9070 GRE. The Instinct MI300A has no benchmark scores listed, an average benchmark score of 0, and a percentile ranking of 50 among all GPUs. The Radeon RX 9070 GRE, by contrast, holds two recorded benchmark results: a 3DMark Steel Nomad DX12 score of 5424 and a Geekbench OpenCL score of 109309. Its average benchmark score sits at 57367, placing it in the 87th percentile of all GPUs. That percentile gap, 87 versus 50, indicates that the RX 9070 GRE occupies a substantially higher position in the database's overall performance distribution.

The RX 9070 GRE's average score of 57367 places it narrowly ahead of several nearest rivals. The Intel Arc A580 trails by only 0.7 percent with an average score of 57756, while the AMD Radeon RX 5600 OEM sits 1.2 percent behind at 58085. The Intel Arc A570M records 58239, a 1.5 percent deficit, and the AMD Radeon RX 6950 XT comes in at 58392, 1.8 percent lower. These margins are tight, meaning the RX 9070 GRE leads its closest competitors by less than two percent in every case. The data shows a cluster of GPUs within a narrow performance band, and the RX 9070 GRE sits at the top of that group by a slim but consistent margin.

Because the Instinct MI300A carries no benchmark entries, no direct score comparison can be made between the two accelerators. The MI300A's zero average benchmark score is not a performance measurement; it reflects the absence of recorded results in the database. The RX 9070 GRE, with its 87th percentile standing and measurable scores across two distinct tests, is the only one of the two with empirical data to analyze. The MI300A's 50th percentile is a default placement rather than a tested outcome.

Architecture Differences

The two chips diverge sharply in design goals. The Instinct MI300A uses the CDNA 3.0 architecture, built on TSMC's 5 nm process, while the RX 9070 GRE uses RDNA 4.0 on a 4 nm node. The MI300A, codenamed Aqua Vanjaram, is a compute-oriented accelerator; the RX 9070 GRE, using the Navi 48 chip, is a graphics card in the Radeon RX 9000 series. The MI300A belongs to the Instinct (MIx) generation, whereas the RX 9070 GRE belongs to the Navi IV (RX 9000) generation.

Transistor counts show the scale difference. The MI300A packs 153,000 million transistors across a 1017 mm² die, yielding a density of 150.4 million transistors per square millimeter. The RX 9070 GRE contains 53,900 million transistors on a 357 mm² die, with a density of 151.0 million per square millimeter. The density figures are nearly identical, which reflects the similar process maturity, but the MI300A's die is roughly 2.8 times larger in area and carries nearly three times the transistor count.

Memory configurations could hardly be more different. The MI300A uses 128 GB of HBM3 on an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The RX 9070 GRE uses 12 GB of GDDR6 on a 192-bit bus, with 432.0 GB/s of bandwidth. The MI300A's memory bandwidth is more than twelve times higher, a direct consequence of its wide HBM interface versus the narrow GDDR6 bus. The RX 9070 GRE's memory clock is listed at 2250 MHz with 18 Gbps effective speed; the MI300A's memory clock is 1300 MHz with 5.2 Gbps effective. The effective data rate favors the GDDR6 part, but the sheer bus width of the HBM3 implementation overwhelms that advantage in total bandwidth.

Compute resources follow the same pattern. The MI300A carries 14592 shading units, 912 texture mapping units, and zero ROPs. Its pixel rate is listed as 0 MPixel/s, and its texture rate reaches 1,915.2 GTexel/s. The RX 9070 GRE has 3072 shading units, 192 TMUs, 96 ROPs, and 48 ray tracing cores. Its pixel rate is 267.8 GPixel/s, and its texture rate is 535.7 GTexel/s. The MI300A has roughly 4.75 times the shading units and 4.75 times the TMUs, but it has no ROPs and no RT cores, confirming its role as a compute accelerator rather than a rasterization engine. FP32 throughput tells the same story: 61.29 TFLOPS for the MI300A versus 34.28 TFLOPS for the RX 9070 GRE. The RX 9070 GRE also lists FP16 at 34.28 TFLOPS with a 1:1 ratio, while the MI300A lists no FP16 figure.

Clock speeds favor the RX 9070 GRE. Its base clock is 1420 MHz, its game clock is 2220 MHz, and its boost clock reaches 2790 MHz. The MI300A has a 1000 MHz base and a 2100 MHz boost. Despite the lower clocks, the MI300A's massive shader count produces higher aggregate throughput.

API support is another separation point. The RX 9070 GRE supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300A lists N/A for DirectX, OpenGL, and Vulkan, which aligns with its lack of display outputs. The MI300A has no display outputs at all; the RX 9070 GRE provides 1x HDMI 2.1b and 3x DisplayPort 2.1a.

Physical and power characteristics differ accordingly. The MI300A is an OAM Module with a 750 W TDP, no power connectors, and a suggested PSU of 1150 W. The RX 9070 GRE is a dual-slot card with 2x 8-pin power connectors, a 220 W TDP, and a suggested PSU of 550 W. The MI300A's power envelope is more than three times larger, consistent with its much larger die and memory subsystem. Both use a PCIe 5.0 x16 bus interface.

The Verdict

The data supports a clear split based on intended use. The Instinct MI300A is a compute accelerator with no display outputs, no rasterization hardware, no graphics API support, and no recorded benchmarks. Its 128 GB HBM3 pool, 5.32 TB/s bandwidth, and 61.29 TFLOPS FP32 throughput target data center workloads. The RX 9070 GRE, with 12 GB GDDR6, 96 ROPs, 48 RT cores, full graphics API coverage, and a 87th percentile benchmark standing, is a client graphics card.

For buyers needing a rendering card with measurable gaming and OpenCL performance, the RX 9070 GRE is the only option with supporting data. Its average benchmark score of 57367 places it ahead of the Intel Arc A580, RX 5600 OEM, Arc A570M, and RX 6950 XT by margins ranging from 0.7 to 1.8 percent. The MI300A cannot be evaluated on the same terms because the database contains no benchmark results for it.

For compute acceleration, the MI300A's specifications indicate extreme memory capacity and bandwidth, along with a shader count and FP32 rate roughly 1.8 times higher than the RX 9070 GRE. The absence of ROPs, RT cores, and display outputs, combined with the OAM form factor and 750 W TDP, marks it as a server-class part. The RX 9070 GRE, by contrast, has a 220 W TDP and dual-slot design suited to a desktop chassis.

Neither part is a substitute for the other. The MI300A cannot output video, and the RX 9070 GRE lacks the memory bandwidth and capacity for large-scale compute. The recorded data gives the RX 9070 GRE a measurable performance profile; the MI300A remains defined entirely by its architecture and specifications.
