AMD Instinct MI300X vs AMD Radeon RX 9060 XT LP Comparison

Head-to-Head Benchmarks

The recorded database contains a single direct comparison between these two accelerators, and the result is decisive. In the Geekbench OpenCL test, the AMD Instinct MI300X scores 317994, while the AMD Radeon RX 9060 XT LP scores 88183. This gives the MI300X a 260.6% advantage, meaning it delivers roughly 3.6 times the compute throughput of the RX 9060 XT LP in this workload.

The MI300X's score places it at the 100th percentile among all GPUs in the database. Its nearest recorded rivals include the NVIDIA B200 at 345482 (8% higher), the NVIDIA H200 NVL at 334891 (5% higher), the NVIDIA L40S at 295763 (7.5% lower), and the NVIDIA RTX 6000 Ada Generation at 287237 (10.7% lower). The MI300X sits squarely between the H200 and the L40S, outperforming the L40S and RTX 6000 Ada by significant margins while trailing the B200 and H200.

The RX 9060 XT LP, by contrast, sits at the 89th percentile. Its average score across all recorded benchmarks is 63830, reflecting two tests: the OpenCL result of 88183 and a Vulkan result of 39476. Its nearest rivals are tightly clustered: the NVIDIA CMP 30HX at 63842 (0% difference), the AMD Radeon RX 7600M at 63775 (0.1% higher), the AMD Radeon Pro Vega 56 at 63693 (0.2% higher), and the AMD Radeon Pro WX 9100 at 64212 (0.6% lower). The RX 9060 XT LP is essentially tied with these cards in average score, indicating it competes in a very different performance tier than the MI300X.

The delta between the two cards in the head-to-head OpenCL test dwarfs any delta found among their respective rival groups. The MI300X holds a 260.6% lead over the RX 9060 XT LP, whereas the largest gap among the MI300X's rivals is 18.7 percentage points (between the B200 and RTX 6000 Ada), and the largest among the RX 9060 XT LP's rivals is just 0.8 percentage points. This suggests the two cards serve entirely separate performance classes.

Architecture Differences

The architectural gulf between these two AMD products is substantial. The MI300X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, fabricated on a 5 nm TSMC process. It contains 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4 million per mm². The RX 9060 XT LP uses the Navi 44 chip built on RDNA 4.0 architecture, fabricated on a 4 nm TSMC process. It contains 29,700 million transistors on a 199 mm² die, giving a transistor density of 149.2 million per mm². The density figures are nearly identical, but the MI300X packs roughly 5.2 times the transistors onto a die that is about 5.1 times larger.

The MI300X is an accelerator with no display outputs, no graphics API support (DirectX, OpenGL, and Vulkan are all listed as N/A), and a pixel rate of 0 MPixel/s. Its shading units number 19456, its texture mapping units number 1216, and it has 0 ROPs. The RX 9060 XT LP is a conventional graphics card with 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and it provides 1x HDMI 2.1b and 2x DisplayPort 2.1a outputs.

Memory configurations diverge sharply. The MI300X carries 192 GB of HBM3 on an 8192-bit bus, with memory clocked at 1300 MHz (5.2 Gbps effective) and bandwidth of 5.32 TB/s. The RX 9060 XT LP carries 16 GB of GDDR6 on a 128-bit bus, with memory clocked at 2518 MHz (20.1 Gbps effective) and bandwidth of 322.3 GB/s. The MI300X offers 12 times the memory capacity and roughly 16.5 times the memory bandwidth.

Clock speeds tell a different story. The RX 9060 XT LP runs at a base of 1380 MHz and boosts to 3050 MHz, with a game clock of 2450 MHz. The MI300X runs at a base of 1000 MHz and boosts to 2100 MHz. The RX 9060 XT LP's higher clocks reflect its graphics-oriented design, while the MI300X relies on massive parallelism and memory bandwidth rather than raw clock speed.

Compute throughput figures highlight the scale difference. The MI300X delivers 81.72 TFLOPS FP32 and 81.72 TFLOPS FP16 (1:1 ratio), with a texture rate of 2,553.6 GTexel/s. The RX 9060 XT LP delivers 24.99 TFLOPS FP32 and 24.99 TFLOPS FP16 (1:1), with a texture rate of 390.4 GTexel/s and a pixel rate of 195.2 GPixel/s. The MI300X leads in FP32 and FP16 by roughly 3.3 times and in texture rate by roughly 6.5 times, but it cannot rasterize at all.

Power and physical design also differ. The MI300X has a TDP of 750 W, uses an OAM module slot width, requires no power connectors, and needs a suggested 1150 W PSU. The RX 9060 XT LP has a TDP of 140 W, is a dual-slot card with a single 8-pin connector, and needs a suggested 300 W PSU. The MI300X draws over 5 times the power and is a server module, while the RX 9060 XT LP is a low-profile desktop card. The RX 9060 XT LP's production status is listed as Active; the MI300X's status is not specified.

Where Each One Wins

The MI300X wins decisively in raw compute. Its OpenCL score of 317994 versus 88183 is the only head-to-head benchmark in the database, and it wins that test outright. Its 260.6% lead indicates that any workload dominated by FP32 or FP16 arithmetic, memory bandwidth, or massive parallel throughput will favor the MI300X heavily. The 192 GB HBM3 pool and 5.32 TB/s bandwidth make it suited for large models and datasets that would not fit in the RX 9060 XT LP's 16 GB GDDR6 frame buffer.

The RX 9060 XT LP wins in areas that the MI300X cannot address at all. It has display outputs, ray tracing cores, and full graphics API support, whereas the MI300X has no outputs and no graphics APIs. The RX 9060 XT LP's 64 ROPs and 195.2 GPixel/s pixel rate enable rasterization; the MI300X has 0 ROPs and 0 MPixel/s. For any rendering, display, or ray-traced workload, the RX 9060 XT LP is the only viable option of the two.

The RX 9060 XT LP also wins on efficiency metrics inferred from the data. Its 140 W TDP versus 750 W means it delivers its 24.99 TFLOPS at a fraction of the power draw. The suggested PSU requirement of 300 W versus 1150 W reinforces that the RX 9060 XT LP fits into far smaller systems. Its dual-slot form factor and single 8-pin connector contrast with the MI300X's OAM module and no connectors, which requires a server chassis.

The RX 9060 XT LP's Vulkan score of 39476 further indicates graphics-oriented capability, since the MI300X has no Vulkan support recorded. The RX 9060 XT LP's average score of 63830 places it near the NVIDIA CMP 30HX, RX 7600M, Radeon Pro Vega 56, and Radeon Pro WX 9100, all within 0.6% to 0.2% of each other. This suggests it is a mid-range performer in the broader database, while the MI300X sits at the absolute top.

The Verdict

The data points to two accelerators with no meaningful overlap. The MI300X is a compute monster: 81.72 TFLOPS FP32, 192 GB HBM3, 5.32 TB/s bandwidth, and an OpenCL score of 317994 that places it at the 100th percentile. It beats the RX 9060 XT LP by 260.6% in the only shared benchmark and outperforms the NVIDIA L40S by 7.5% and the RTX 6000 Ada by 10.7%. It trails only the NVIDIA B200 and H200 NVL among its recorded rivals. Anyone selecting the MI300X is choosing maximum compute throughput for non-graphics workloads.

The RX 9060 XT LP is a different class entirely. Its 24.99 TFLOPS FP32, 16 GB GDDR6, and 322.3 GB/s bandwidth serve graphics and display workloads. Its 89th percentile ranking and average score of 63830 place it alongside mining and professional cards like the CMP 30HX and WX 9100, not alongside data center accelerators. It has ray tracing cores, display outputs, and full API support, none of which the MI300X offers.

The verdict follows directly: the MI300X suits compute-heavy, headless server workloads where power draw and form factor are secondary. The RX 9060 XT LP suits graphics, rendering, and desktop use where display output, ray tracing, and low power draw matter. The recorded data offers no scenario where both cards compete for the same role.
