AMD Instinct MI300X vs NVIDIA GeForce RTX 4060 AD106 Comparison

The Verdict

The database places the AMD Instinct MI300X and NVIDIA GeForce RTX 4060 AD106 in entirely different performance strata. The MI300X sits at the 100th percentile of all GPUs, while the RTX 4060 sits at the 50th percentile. The MI300X delivers a recorded Geekbench OpenCL score of 317,994, whereas the RTX 4060 has no benchmark entry in the database, resulting in an average score of zero. This is not a comparison of equals; it is a comparison of a data center accelerator against a consumer graphics card.

The MI300X is for compute environments where massive memory capacity and raw FP32 throughput are the priority. The RTX 4060 AD106 is for desktop systems requiring display outputs, ray tracing, and standard graphics APIs. The MI300X has no display outputs and reports zero pixel rate, making it unsuitable for any visual output. The RTX 4060 provides 1x HDMI 2.1 and 3x DisplayPort 1.4a, along with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support. The MI300X lists N/A for all three graphics APIs.

The power envelope tells a similar story. The MI300X carries a 750 W TDP with a suggested PSU of 1150 W, while the RTX 4060 uses 115 W with a 300 W suggested PSU. The MI300X is an OAM module with no power connectors listed; the RTX 4060 is a dual-slot card using a single 12-pin connector. The data indicates the MI300X is a server-room component, not a desktop part.

Architecture Differences

The MI300X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, manufactured by TSMC on a 5 nm process. It packs 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². The RTX 4060 uses the AD106 chip on Ada Lovelace architecture, also TSMC 5 nm, but with 22,900 million transistors on a 188 mm² die, giving 121.8M per mm². The MI300X die is over five times larger and holds nearly seven times more transistors.

Memory architecture diverges sharply. The MI300X uses 192 GB of HBM3 on an 8192-bit bus, producing 5.32 TB/s of bandwidth. The RTX 4060 uses 8 GB of GDDR6 on a 128-bit bus, producing 272.0 GB/s. The MI300X has roughly 19.6 times the memory bandwidth of the RTX 4060. The MI300X memory clock is 1300 MHz with 5.2 Gbps effective, while the RTX 4060 memory runs at 2125 MHz with 17 Gbps effective.

Compute resources differ by an order of magnitude. The MI300X has 19,456 shading units, 1,216 TMUs, and zero ROPs. The RTX 4060 has 3,072 shading units, 96 TMUs, and 48 ROPs. The RTX 4060 carries 24 ray tracing cores and 96 tensor cores; the MI300X lists no RT or tensor core counts. The MI300X reports 0 MPixel/s pixel rate and 2,553.6 GTexel/s texture rate, while the RTX 4060 reports 118.1 GPixel/s and 236.2 GTexel/s.

Clock behavior also differs. The MI300X has a 1000 MHz base and 2100 MHz boost. The RTX 4060 has a 1830 MHz base and 2460 MHz boost. Despite lower clocks, the MI300X produces 81.72 TFLOPS FP32 and 81.72 TFLOPS FP16 (1:1). The RTX 4060 produces 15.11 TFLOPS FP32 and 15.11 TFLOPS FP16 (1:1). The MI300X delivers roughly 5.4 times the FP32 throughput.

Head-to-Head Benchmarks

The only benchmark recorded for the MI300X is Geekbench OpenCL, where it scores 317,994. The RTX 4060 has no recorded benchmark score in the database, so direct numerical comparison is impossible. The database places the MI300X at the 100th percentile of all GPUs, while the RTX 4060 sits at the 50th percentile. That percentile gap is the clearest available indicator of relative performance.

The MI300X nearest rivals show where it actually competes: NVIDIA H200 NVL scores 334,891 (5% higher), NVIDIA B200 scores 345,482 (8% higher), NVIDIA L40S scores 295,763 (7.5% lower), and NVIDIA RTX 6000 Ada Generation scores 287,237 (10.7% lower). The MI300X sits between these data center parts, closer to the L40S and RTX 6000 than to the H200 or B200. The RTX 4060 has no nearest rivals listed, so its competitive context is limited to its percentile rank.

The texture rate comparison is notable. The MI300X reports 2,553.6 GTexel/s versus 236.2 GTexel/s for the RTX 4060, a roughly 10.8 times difference. The MI300X has no pixel output, while the RTX 4060 processes 118.1 GPixel/s. These numbers confirm that the MI300X is optimized for compute throughput, not rasterization.

Where Each One Wins

The MI300X wins decisively in raw compute throughput, memory capacity, and memory bandwidth. Its 81.72 TFLOPS FP32 output and 81.72 TFLOPS FP16 output are unmatched by the RTX 4060's 15.11 TFLOPS in both precisions. The 192 GB HBM3 pool with 5.32 TB/s bandwidth supports workloads that cannot fit in the RTX 4060's 8 GB GDDR6 buffer. The 2,553.6 GTexel/s texture rate is over ten times the RTX 4060's 236.2 GTexel/s. The MI300X also wins on interface generation, using PCIe 5.0 x16 versus the RTX 4060's PCIe 4.0 x8.

The RTX 4060 wins in every area related to conventional graphics output. It has 48 ROPs and a 118.1 GPixel/s pixel rate, while the MI300X has zero ROPs and zero pixel rate.

The RTX 4060 includes 24 ray tracing cores and 96 tensor cores, features absent from the MI300X record. The RTX 4060 also has a much lower power draw at 115 W versus 750 W, and it fits in a dual-slot form factor with a standard 12-pin connector.

The RTX 4060 wins on clock speeds, with a 1830 MHz base and 2460 MHz boost against the MI300X's 1000 MHz base and 2100 MHz boost.
