AMD Instinct MI300 vs AMD Playstation 5 Pro GPU Comparison

AMD Instinct MI300 and AMD Playstation 5 Pro GPU represent two entirely different design philosophies from the same manufacturer. The MI300 is a data center accelerator built for massive compute throughput, while the PS5 Pro GPU is a console part optimized for a fixed gaming environment. Benchmark results from the database show no direct head-to-head measurements, so the comparison relies on the recorded architectural specifications and performance indicators.

Head-to-Head Benchmarks

The database contains no direct benchmark scores for either GPU, with both units showing zero recorded results and an average benchmark score of zero. The percentileVsAllGpus field places both at the 50th percentile, indicating that no meaningful performance ranking can be derived from actual testing data. Without measured frame rates, compute scores, or synthetic test results, the comparison must be based entirely on the raw throughput figures listed in the specifications.

The FP32 compute figures show the MI300 delivering 47.87 TFLOPS, which is 2.65 times the 18.05 TFLOPS of the PS5 Pro GPU. This represents the largest single gap between the two parts in raw compute capability. For FP16 workloads, the MI300 again leads with 47.87 TFLOPS at a 1:1 ratio, while the PS5 Pro GPU achieves 36.10 TFLOPS at a 2:1 ratio. The FP16 advantage for the MI300 is 1.33 times, a smaller margin than the FP32 difference but still substantial.

Texture processing favors the MI300 heavily. The MI300 delivers 1,496.0 GTexel/s against 564.0 GTexel/s for the PS5 Pro GPU, a 2.65 times advantage. This aligns with the shading unit count: 14,080 for the MI300 versus 3,840 for the PS5 Pro GPU, a ratio of 3.67 to 1. The TMU count follows at 880 versus 240, a 3.67 to 1 ratio as well.

Pixel throughput reverses the trend. The PS5 Pro GPU outputs 150.4 GPixel/s, while the MI300 records 0 MPixel/s. This is a fundamental design difference: the MI300 has no ROPs and no display outputs, making it incapable of rasterizing frames for display. The PS5 Pro GPU has 64 ROPs and a pixel rate of 150.4 GPixel/s, which is a standard configuration for a gaming console.

Memory bandwidth strongly favors the MI300. It uses 128 GB of HBM3 across an 8192-bit bus, delivering 5.32 TB/s of bandwidth. The PS5 Pro GPU uses 16 GB of GDDR6 across a 256-bit bus, delivering 576.0 GB/s. The MI300 bandwidth advantage is 9.24 times. This reflects the different memory architectures: HBM3 stacked memory for compute workloads versus GDDR6 for gaming.

Clock speeds show the PS5 Pro GPU running significantly higher. The PS5 Pro GPU has a base clock of 2170 MHz and a boost clock of 2350 MHz, while the MI300 operates at 1000 MHz base and 1700 MHz boost. The PS5 Pro GPU boost clock is 1.38 times higher than the MI300 boost clock. The memory clock also favors the PS5 Pro GPU at 2250 MHz (18 Gbps effective) versus 1300 MHz (5.2 Gbps effective) for the MI300.

Architecture Differences

The MI300 uses the CDNA 3.0 architecture on TSMC 5 nm process, while the PS5 Pro GPU uses RDNA 2.0 on TSMC 4 nm process. The process node difference is 4 nm versus 5 nm, with the PS5 Pro GPU on the smaller node. The MI300 chip, codenamed Aqua Vanjaram, contains 153,000 million transistors on a 1017 mm² die, resulting in a transistor density of 150.4M per mm². The PS5 Pro GPU chip, codenamed Viola, contains 21,000 million transistors on a 279 mm² die, with a density of 75.3M per mm². The MI300 has 7.29 times more transistors and a die that is 3.65 times larger.

The transistor density difference is notable: 150.4M per mm² for the MI300 versus 75.3M per mm² for the PS5 Pro GPU. Despite the PS5 Pro GPU using a smaller 4 nm node, the MI300 achieves nearly double the density. This is consistent with the MI300 being an accelerator with dense compute arrays rather than a graphics-oriented design with rasterization hardware.

The MI300 has 14,080 shading units, 880 TMUs, and 0 ROPs. The PS5 Pro GPU has 3,840 shading units, 240 TMUs, and 64 ROPs. The MI300 dedicates all its silicon to compute and texture work, while the PS5 Pro GPU reserves resources for pixel output. The MI300 has no display outputs, while the PS5 Pro GPU provides 1x HDMI 2.1 and 1x USB Type-C.

API support differs completely. The MI300 lists DirectX, OpenGL, and Vulkan as N/A, confirming it is not designed for graphics rendering. The PS5 Pro GPU lists OpenGL 4.6 and Vulkan 1.2, with DirectX as N/A. The PS5 Pro GPU also has a production status of Active, while the MI300 has no production status recorded.

Memory configuration is a major architectural split. The MI300 uses 128 GB of HBM3 with an 8192-bit bus and 5.32 TB/s bandwidth. The PS5 Pro GPU uses 16 GB of GDDR6 with a 256-bit bus and 576.0 GB/s bandwidth. The MI300 has 8 times the memory capacity and 32 times the bus width. The FP16 ratio also differs: the MI300 runs FP16 at 1:1 with FP32, while the PS5 Pro GPU runs FP16 at 2:1, meaning the MI300 dedicates equal throughput to both precision levels.

Power and physical specifications diverge sharply. The MI300 has a TDP of 600 W, uses 2x 8-pin power connectors, and requires a suggested PSU of 1000 W. The PS5 Pro GPU has a TDP of 232 W, no recorded power connectors, and no suggested PSU. The MI300 uses 2.59 times the power of the PS5 Pro GPU. Physically, the MI300 measures 267 mm by 111 mm with a 10.5 inch length and 4.4 inch height. The PS5 Pro GPU measures 386 mm by 216 mm by 89 mm, with 15.2 inch length, 8.5 inch height, and 3.5 inch width.

The bus interface also differs. The MI300 uses PCIe 5.0 x16, while the PS5 Pro GPU has no recorded bus interface, reflecting its fixed console integration. Release dates show the MI300 launching on 2023-01-03 and the PS5 Pro GPU on 2024-11-06, a gap of roughly 22 months. The MI300 predecessor is listed as Radeon Instinct, while the PS5 Pro GPU has no predecessor recorded. No successors are listed for either.

Where Each One Wins

The MI300 wins in compute-heavy workloads due to its 47.87 TFLOPS FP32 and FP16 performance. The 2.65 times FP32 advantage over the PS5 Pro GPU makes it suited for tasks like scientific simulation, AI training, and data center compute. The 5.32 TB/s memory bandwidth, 9.24 times the PS5 Pro GPU, supports large datasets that exceed the 16 GB capacity of the console part. The 128 GB HBM3 memory allows fitting entire models or datasets in memory without host transfers.

The PS5 Pro GPU wins in gaming and display-oriented workloads. Its 150.4 GPixel/s pixel rate and 64 ROPs enable actual frame rendering, which the MI300 cannot do with its 0 MPixel/s and no display outputs. The PS5 Pro GPU delivers 18.05 TFLOPS FP32, which is a capable baseline for console gaming. The higher clock speeds of 2350 MHz boost versus 1700 MHz boost suggest the PS5 Pro GPU runs at a faster rate per shader, even though it has far fewer shaders. The 576.0 GB/s bandwidth is a standard console-class figure.

The PS5 Pro GPU also wins on efficiency per watt in the context of its design. At 232 W TDP versus 600 W, it uses 38.7 percent of the power of the MI300 (this calculation is based on the recorded TDP values: 232 divided by 600 equals 0.3867). The FP32 per watt ratio is 0.0778 TFLOPS per watt for the PS5 Pro GPU and 0.0798 TFLOPS per watt for the MI300, so the efficiency is nearly identical, with the MI300 having a marginal 1.03 times edge in FP32 per watt. However, the PS5 Pro GPU includes rasterization hardware and display outputs, which the MI300 lacks entirely.

The FP16 ratio difference gives the MI300 an edge in mixed-precision workloads. The MI300 runs FP16 at 1:1, meaning its FP16 throughput equals its FP32 throughput at 47.87 TFLOPS. The PS5 Pro GPU runs FP16 at 2:1, doubling its FP16 throughput to 36.10 TFLOPS. In workloads that use FP16, the MI300 still leads by 1.33 times, but the PS5 Pro GPU gets a 2 times boost over its FP32 figure, which narrows the gap.
