AMD Instinct MI455X vs NVIDIA GeForce RTX 5060 Comparison

The Verdict

The database contains two fundamentally different products: the AMD Instinct MI455X, an enterprise accelerator with no recorded benchmark scores, and the NVIDIA GeForce RTX 5060, a consumer graphics card with a full benchmark suite. The RTX 5060 holds the 72nd percentile among all GPUs, while the MI455X sits at the 50th percentile with an average benchmark score of zero. The data indicates the RTX 5060 is the only option for anyone needing measurable graphics or compute performance. The MI455X, with its 432 GB of HBM4 memory and 23.3 TB/s bandwidth, targets workloads where capacity and bandwidth matter, but the recorded database contains no application results to quantify that advantage. The RTX 5060 delivers 19.18 TFLOPS FP32, 30 RT cores, and a 12 Ultimate DirectX feature level, making it appropriate for gaming and mainstream compute tasks. The MI455X lacks display outputs entirely, which removes it from consideration for any interactive graphics use case.

Architecture Differences

The two chips diverge at nearly every architectural level. The MI455X uses AMD's CDNA 5.0 architecture on a 2 nm TSMC process, while the RTX 5060 uses NVIDIA's Blackwell 2.0 architecture on a 5 nm TSMC process. Transistor counts differ dramatically: the MI455X integrates 320,000 million transistors across a 2990 mm² die, whereas the RTX 5060 packs 21,900 million transistors into an 181 mm² die. Transistor density tells a different story, with the RTX 5060 at 121.0M per mm² compared to the MI455X at 107.0M per mm², indicating the NVIDIA chip achieves higher packing density despite the older process node.

The MI455X employs a massive MI450 256CU configuration with 32,768 shading units, 1,024 texture mapping units, and zero raster operation units. Its pixel rate is recorded as 0 MPixel/s, confirming it is not designed for rasterization. The RTX 5060 uses the GB206 chip with 3,840 shading units, 120 TMUs, and 48 ROPs, producing a 119.9 GPixel/s pixel rate. The RTX 5060 includes 30 RT cores and 120 tensor cores, while the MI455X has no recorded RT or tensor core counts. The MI455X's texture rate reaches 2,457.6 GTexel/s against the RTX 5060's 299.6 GTexel/s, reflecting the accelerator's focus on raw throughput rather than graphics pipeline work.

Memory subsystems could not be more different. The MI455X carries 432 GB of HBM4 across a 24,576-bit bus, yielding 23.3 TB/s bandwidth. The RTX 5060 uses 8 GB of GDDR7 on a 128-bit bus for 448.0 GB/s. Clock behavior also diverges: the MI455X runs at a 1000 MHz base and 2400 MHz boost, while the RTX 5060 starts at 2280 MHz base and reaches 2497 MHz boost. The MI455X's memory clock is 1900 MHz with 7.6 Gbps effective, compared to the RTX 5060's 1750 MHz memory clock at 28 Gbps effective.

Where Each One Wins

The RTX 5060 wins in every measurable benchmark category because the MI455X has no recorded scores. The RTX 5060 achieves its highest single-test result in Geekbench Vulkan with 113,321 points, followed closely by Geekbench OpenCL at 112,787. PassMark G3D shows 20,891 points, and PassMark GPU Compute reaches 10,899. The 3DMark Steel Nomad DX12 test returns 3,628 points. DirectX 9 and DirectX 11 results are 225 and 200 points respectively, with DirectX 10 at 127 and DirectX 12 at 77. The 2D test produces 1,154 points.

The MI455X's only recorded strengths are architectural. Its 432 GB memory capacity exceeds the RTX 5060's 8 GB by a factor of 54, and its 23.3 TB/s bandwidth is 52 times higher. FP32 throughput of 157.3 TFLOPS dwarfs the RTX 5060's 19.18 TFLOPS. Texture rate of 2,457.6 GTexel/s is 8.2 times the RTX 5060's 299.6 GTexel/s. The MI455X also supports PCIe 6.0 x16, while the RTX 5060 uses PCIe 5.0 x8. These figures suggest the MI455X is built for memory-bound or throughput-bound server workloads, but the database provides no application-level verification.

The RTX 5060 offers display connectivity with 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs, while the MI455X has none. The RTX 5060 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, whereas the MI455X lists N/A for all three APIs. The RTX 5060 is a dual-slot card measuring 241 mm long, 111 mm high, and 40 mm wide, with a single 8-pin power connector and a 300 W suggested PSU. The MI455X is an EAM Module form factor with no power connectors and a 2,700 W suggested PSU.
