AMD Radeon Instinct MI300A vs AMD Ryzen Z2 A GPU Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark matches for the AMD Radeon Instinct MI300A and the AMD Ryzen Z2 A GPU. Both entries show an average benchmark score of zero and a percentile rank of 50 among all GPUs. This absence of measured performance data means any comparison must rely entirely on the recorded hardware specifications and architectural details.

The MI300A posts an FP32 throughput of 81.72 TFLOPS, while the Ryzen Z2 A GPU delivers 1.638 TFLOPS. That difference is substantial, roughly 50 times higher on the Instinct side. In FP16 compute, the MI300A reaches 653.7 TFLOPS (8:1 ratio), whereas the Ryzen Z2 A GPU produces 3.277 TFLOPS (2:1 ratio). The Instinct part delivers nearly 200 times the half-precision throughput.

Texture rate follows a similar pattern. The MI300A records 2,553.6 GTexel/s, compared to 51.20 GTexel/s for the Ryzen Z2 A GPU. Pixel rate tells a different story: the MI300A lists 0 MPixel/s, while the Ryzen Z2 A GPU manages 25.60 GPixel/s. The Instinct accelerator has no ROPs recorded, which explains its zero pixel throughput.

Memory bandwidth heavily favors the MI300A. It uses 192 GB of HBM3 across an 8192-bit bus, yielding 10.3 TB/s. The Ryzen Z2 A GPU uses 16 GB of LPDDR5 on a 128-bit bus, producing 102.4 GB/s. The Instinct part offers roughly 100 times the bandwidth.

Clock speeds show the MI300A boosting to 2100 MHz, while the Ryzen Z2 A GPU boosts to 1600 MHz. Both share a 1000 MHz base clock. The MI300A memory runs at 2525 MHz (10.1 Gbps effective), while the Ryzen Z2 A GPU memory runs at 800 MHz (6.4 Gbps effective).

Where Each One Wins

The MI300A dominates in raw compute throughput, memory capacity, memory bandwidth, texture rate, and transistor count. Its 153,000 million transistors on a 1017 mm² die dwarf the Ryzen Z2 A GPU's 2,400 million transistors on a 163 mm² die. The MI300A also has far more shading units (19,456 vs 512) and TMUs (1,216 vs 32).

The Ryzen Z2 A GPU wins in areas tied to graphics output and power efficiency. It has 16 ROPs, enabling 25.60 GPixel/s pixel fill, and it supports display output via 1x USB Type-C. The MI300A has no display outputs. The Ryzen Z2 A GPU also consumes far less power, with a 15 W TDP versus 750 W for the MI300A. Its 7 nm process node, while larger than the MI300A's 5 nm node, still allows a much lower power envelope.

The Ryzen Z2 A GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The MI300A lists no API support in the database, consistent with its role as a compute accelerator rather than a graphics card.

The MI300A carries a suggested PSU rating of 1150 W and uses an OAM Module slot width with no power connectors. The Ryzen Z2 A GPU has no PSU suggestion and no slot width recorded.

Architecture Differences

The MI300A uses CDNA 3.0, AMD's compute-oriented architecture designed for data center acceleration. The Ryzen Z2 A GPU uses RDNA 2.0, AMD's graphics architecture aimed at rendering and gaming workloads. This fundamental split explains many of the observed specification gaps.

The MI300A has no ray tracing cores recorded, while the Ryzen Z2 A GPU includes 8. RDNA 2.0 includes hardware ray acceleration, a feature CDNA 3.0 does not prioritize. The MI300A also lacks ROPs entirely, confirming it performs no traditional rasterization. The Ryzen Z2 A GPU has 16 ROPs and a pixel rate of 25.60 GPixel/s.

The MI300A's memory subsystem uses HBM3 stacked memory with a massive 8192-bit interface. This configuration targets high-bandwidth compute workloads. The Ryzen Z2 A GPU uses LPDDR5 system memory on a 128-bit bus, typical for low-power integrated graphics.

The MI300A's transistor density of 150.4M / mm² reflects the 5 nm process and massive die. The Ryzen Z2 A GPU's density of 14.7M / mm² on 7 nm is much lower. The MI300A die area of 1017 mm² makes it one of the largest recorded in the database.

Power delivery differs sharply. The MI300A draws 750 W and suggests a 1150 W PSU, with an OAM Module form factor. The Ryzen Z2 A GPU draws only 15 W and has no external power requirements recorded. The MI300A uses PCIe 5.0 x16, while the Ryzen Z2 A GPU lists no bus interface.

The MI300A belongs to the Radeon Instinct generation, with a predecessor of FirePro Data Center. The Ryzen Z2 A GPU belongs to the Console GPU generation and has no predecessor recorded. The MI300A released on 2023-12-05, nearly a year before the Ryzen Z2 A GPU's 2024-12-31 release date. The Ryzen Z2 A GPU remains in active production, while the MI300A's production status is not recorded.
