AMD Instinct MI300X vs NVIDIA GeForce RTX 4060 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains a single direct comparison between the AMD Instinct MI300X and the NVIDIA GeForce RTX 4060 Mobile: the Geekbench OpenCL test. In this benchmark, the AMD Instinct MI300X scores 317,994 points, while the NVIDIA GeForce RTX 4060 Mobile scores 89,420 points. This results in a delta of 255.6% in favor of the AMD part, meaning the MI300X delivers more than three and a half times the OpenCL performance of the mobile RTX 4060 in this workload. This is not a marginal advantage; it is a categorical difference in compute throughput.

The MI300X's average benchmark score across its recorded results is 317,994, placing it at the 100th percentile of all GPUs in the database. Its nearest rivals in the database are all enterprise data center accelerators: the NVIDIA B200 at 345,482 points (8% higher), the NVIDIA H200 NVL at 334,891 points (5% higher), the NVIDIA L40S at 295,763 points (7.5% lower), and the NVIDIA RTX 6000 Ada Generation at 287,237 points (10.7% lower). The MI300X sits comfortably within this high-end compute cluster, ahead of two of its four nearest rivals and trailing the top two by single-digit percentages.

The RTX 4060 Mobile, by contrast, has an average benchmark score of 22,729, placing it at the 67th percentile of all GPUs. Its nearest rivals are a much more mainstream set of parts: the NVIDIA GeForce RTX 2080 at 22,895 points (0.7% higher), the Intel Arc B580 at 23,021 points (1.3% higher), the AMD Radeon RX 7700 XT at 22,549 points (0.8% lower), and the NVIDIA GeForce RTX 5060 Mobile at 22,435 points (1.3% lower). The RTX 4060 Mobile is essentially tied with these four rivals, with deltas under 1.5% in either direction. This indicates the mobile part is positioned in a dense performance band where small clock and memory differences decide the ranking.

The RTX 4060 Mobile does have additional recorded benchmarks beyond OpenCL. Its Vulkan score is 89,569, nearly identical to its OpenCL result. In the PassMark suite, it scores 17,469 in G3D, 6,816 in GPU Compute, 730 in G2D, 216 in DirectX 9, 157 in DirectX 11, 107 in DirectX 10, and 73 in DirectX 12. The MI300X has no corresponding entries in these tests, so no direct head-to-head comparison is possible for those workloads. The only shared test is OpenCL, and the MI300X wins it decisively.

Where Each One Wins

The AMD Instinct MI300X wins the only shared benchmark, Geekbench OpenCL, by a margin of 255.6%. This result is consistent with its positioning at the 100th percentile of all GPUs, a category that includes only the most powerful compute accelerators in the database. The MI300X's nearest rivals are all data center parts, and it beats two of them outright. Any workload that relies on OpenCL compute throughput will favor the MI300X heavily.

The NVIDIA GeForce RTX 4060 Mobile, by contrast, has no direct benchmark wins against the MI300X because there is no shared test beyond OpenCL. However, the RTX 4060 Mobile does have a broader set of recorded benchmarks, including Vulkan and several PassMark tests. Its Vulkan score of 89,569 is close to its OpenCL score, suggesting consistent performance across different API workloads. The PassMark results show a varied profile: the G3D score of 17,469 is the strongest of the group, while the DirectX 10 score of 107 and DirectX 12 score of 73 are much lower. The MI300X has no recorded data for these tests, so the RTX 4060 Mobile is the only one of the two with measurable results in those areas.

The use-case split is therefore clear. For raw compute performance, particularly in OpenCL, the MI300X is the dominant part. For any workload where the RTX 4060 Mobile's additional benchmark coverage applies, such as DirectX or Vulkan scenarios, it is the only one of the two with recorded data, though no comparison can be made without corresponding MI300X results.

Specification Differences

The two GPUs differ in nearly every measurable specification. The MI300X uses 153,000 million transistors on a 1017 mm² die, while the RTX 4060 Mobile uses 18,900 million transistors on a 159 mm² die. Transistor density is 150.4 million per mm² for the MI300X versus 118.9 million per mm² for the RTX 4060 Mobile.

Memory configurations are vastly different. The MI300X has 192 GB of HBM3 memory on an 8192-bit bus with 5.32 TB/s of bandwidth. The RTX 4060 Mobile has 8 GB of GDDR6 memory on a 128-bit bus with 256.0 GB/s of bandwidth. The MI300X has 19,456 shading units and 1,216 TMUs, while the RTX 4060 Mobile has 3,072 shading units, 96 TMUs, and 48 ROPs. The MI300X has no ROPs, no RT cores, and no tensor cores recorded. The RTX 4060 Mobile has 24 RT cores and 96 tensor cores.

Clock speeds differ as well. The MI300X runs at a base clock of 1000 MHz and a boost clock of 2100 MHz, with memory at 1300 MHz (5.2 Gbps effective). The RTX 4060 Mobile runs at a base clock of 1545 MHz and a boost clock of 1890 MHz, with memory at 2000 MHz (16 Gbps effective). Despite the higher base clock on the RTX 4060 Mobile, the MI300X achieves a higher boost clock.

Compute output is heavily skewed toward the MI300X. It delivers 81.72 TFLOPS of FP32 and the same 81.72 TFLOPS of FP16 (1:1 ratio). The RTX 4060 Mobile delivers 11.61 TFLOPS of FP32 and 11.61 TFLOPS of FP16 (1:1 ratio). Texture rate is 2,553.6 GTexel/s for the MI300X versus 181.4 GTexel/s for the RTX 4060 Mobile. Pixel rate is 0 MPixel/s for the MI300X versus 90.72 GPixel/s for the RTX 4060 Mobile.

Power and form factor also separate the two. The MI300X has a TDP of 750 W, a suggested PSU of 1150 W, and uses an OAM module slot. The RTX 4060 Mobile has a TDP of 115 W, no suggested PSU, and uses an IGP slot. The MI300X has no display outputs, while the RTX 4060 Mobile has outputs described as portable device dependent. The bus interface is PCIe 5.0 x16 for the MI300X and PCIe 4.0 x8 for the RTX 4060 Mobile.

Architecture Differences

The architectural divide is fundamental. The MI300X uses the CDNA 3.0 architecture, built on the Aqua Vanjaram chip, and belongs to the Instinct (MIx) generation. The RTX 4060 Mobile uses the Ada Lovelace architecture, built on the AD107 chip, and belongs to the GeForce 40 Mobile generation. Both are fabricated by TSMC on a 5 nm process, but the design philosophies are entirely different.

The MI300X is a compute-focused accelerator with no display outputs, no raster operations pipelines, and no graphics API support. Its DirectX, OpenGL, and Vulkan support are all listed as N/A. The RTX 4060 Mobile, by contrast, is a full graphics part with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support. It also includes dedicated RT cores and tensor cores, which the MI300X lacks entirely.

The MI300X was released on December 5, 2023, with a predecessor of Radeon Instinct. The RTX 4060 Mobile was released on January 2, 2023, with a predecessor of GeForce 30 Mobile and a successor of GeForce 50 Mobile. The MI300X has no recorded successor. The production status of the MI300X is not recorded, while the RTX 4060 Mobile is listed as active.

Memory architecture reinforces the divide. HBM3 on an 8192-bit bus is designed for maximum bandwidth in compute workloads, while GDDR6 on a 128-bit bus is a conventional graphics memory configuration. The MI300X's 5.32 TB/s of bandwidth is over 20 times the RTX 4060 Mobile's 256.0 GB/s, a gap that directly explains the OpenCL performance difference.

The Verdict

The data indicates two GPUs built for entirely different purposes. The AMD Instinct MI300X is a data center compute accelerator with a 255.6% OpenCL advantage over the NVIDIA GeForce RTX 4060 Mobile. It sits at the 100th percentile of all GPUs, alongside the B200, H200 NVL, L40S, and RTX 6000 Ada Generation. Its 192 GB of HBM3 memory, 81.72 TFLOPS of FP32, and 750 W TDP mark it as a server-class part with no display outputs and no graphics API support.

The NVIDIA GeForce RTX 4060 Mobile is a mainstream laptop GPU at the 67th percentile, trading blows with the RTX 2080, Arc B580, RX 7700 XT, and RTX 5060 Mobile within a 1.3% band. It has 8 GB of GDDR6 memory, 11.61 TFLOPS of FP32, full DirectX 12 Ultimate and Vulkan support, and a 115 W TDP. Its 24 RT cores and 96 tensor cores provide hardware features the MI300X does not have.

Who should pick which depends entirely on the workload. The data supports the MI300X for any OpenCL compute task where raw throughput is the priority. The RTX 4060 Mobile is the only one of the two with recorded results in graphics-oriented benchmarks, and its portable form factor, display outputs, and graphics API coverage make it the only viable choice for client-side rendering workloads. There is no overlap in their recorded performance profiles beyond the single OpenCL test. The MI300X wins that test by a wide margin, and the RTX 4060 Mobile wins by default in every test category where the MI300X has no recorded data.
