AMD Instinct MI355X vs AMD Radeon RX 9060 XT LP Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Instinct MI355X and the AMD Radeon RX 9060 XT LP, and the MI355X has no recorded benchmark scores or nearest rivals. The RX 9060 XT LP, however, holds an average benchmark score of 63830 across its recorded tests, placing it in the 89th percentile of all GPUs. Its nearest rival, the NVIDIA CMP 30HX, scores 63842, a delta of 0%, meaning the two are statistically tied. The AMD Radeon RX 7600M follows at 63775, a 0.1% delta, and the AMD Radeon Pro Vega 56 scores 63693, a 0.2% delta. The AMD Radeon Pro WX 9100 trails slightly at 64212, a -0.6% delta, indicating the RX 9060 XT LP holds a marginal edge over that card.

The RX 9060 XT LP's recorded benchmarks show a Geekbench OpenCL score of 88183 and a Geekbench Vulkan score of 39476. These two figures reveal a substantial gap between compute-oriented workloads and graphics-oriented workloads, with the OpenCL result more than double the Vulkan result. The MI355X, by contrast, has no benchmark entries in the database, so its performance cannot be positioned relative to the RX 9060 XT LP or any other GPU. The MI355X does hold a percentile rank of 50, which is below the RX 9060 XT LP's 89th percentile, but without actual scores, this rank likely reflects the absence of data rather than measured performance.

The wins count stands at 0 for both parts, as no head-to-head tests exist. The data indicates that the RX 9060 XT LP is a measured, competitive product in its segment, while the MI355X remains an unmeasured entry in the database. Any comparison of raw performance between the two must rely on architectural and specification differences rather than direct benchmark outcomes.

Architecture Differences

The MI355X uses the CDNA 4.0 architecture with an MI350 256CU chip, while the RX 9060 XT LP uses RDNA 4.0 with a Navi 44 chip. These are fundamentally different design philosophies. CDNA 4.0 targets compute acceleration, evidenced by the absence of display outputs, no DirectX, OpenGL, or Vulkan API support, and zero ROPs. RDNA 4.0 targets graphics workloads, with full API support including DirectX 12 Ultimate (12_2), OpenGL 4.6, Vulkan 1.4, 64 ROPs, and 32 ray tracing cores.

The process nodes differ: the MI355X is built on TSMC's 3 nm process, while the RX 9060 XT LP uses TSMC's 4 nm process. The MI355X packs 185,000 million transistors on a 2380 mm² die, yielding a transistor density of 77.7 million per mm². The RX 9060 XT LP contains 29,700 million transistors on a 199 mm² die, with a density of 149.2 million per mm². The MI355X has more than six times the transistor count and a die over ten times larger, but the RX 9060 XT LP achieves nearly double the transistor density, reflecting the different design priorities.

Clock speeds tell a similar story. The MI355X has a base clock of 1000 MHz and a boost clock of 2400 MHz. The RX 9060 XT LP has a base clock of 1380 MHz, a game clock of 2450 MHz, and a boost clock of 3050 MHz. The RX 9060 XT LP runs significantly higher clocks, which is typical for a graphics-oriented part, while the MI355X favors lower clocks with massive parallelism.

Memory configurations are radically different. The MI355X offers 288 GB of HBM3e memory on an 8192-bit bus, delivering 8.19 TB/s of bandwidth. The RX 9060 XT LP provides 16 GB of GDDR6 on a 128-bit bus with 322.3 GB/s of bandwidth. The MI355X has over 25 times the memory bandwidth, which is essential for compute workloads, while the RX 9060 XT LP's bandwidth is adequate for graphics at its resolution targets.

Compute resources diverge sharply. The MI355X has 16384 shading units, 1024 TMUs, and 0 ROPs, with a texture rate of 2,457.6 GTexel/s. The RX 9060 XT LP has 2048 shading units, 128 TMUs, and 64 ROPs, with a texture rate of 390.4 GTexel/s and a pixel rate of 195.2 GPixel/s. The MI355X's FP32 throughput is 78.64 TFLOPS, while the RX 9060 XT LP delivers 24.99 TFLOPS. Both parts report FP16 at a 1:1 ratio with FP32.

Power requirements reflect their roles. The MI355X has a TDP of 1400 W with a suggested PSU of 1800 W, while the RX 9060 XT LP has a TDP of 140 W with a suggested PSU of 300 W. The MI355X uses an OAM module slot width with no power connectors, indicating it draws power through the module interface. The RX 9060 XT LP is a dual-slot card with a single 8-pin connector.

The Verdict

The database shows two GPUs with almost no overlap in purpose. The MI355X is a compute accelerator with no display outputs, no graphics API support, and a TDP of 1400 W. It is designed for data center workloads where memory capacity and bandwidth matter more than clocks or rasterization. The RX 9060 XT LP is a graphics card with full API support, display outputs including 1x HDMI 2.1b and 2x DisplayPort 2.1a, and a 140 W TDP, built for conventional graphics tasks.

For users seeking graphics performance, the RX 9060 XT LP is the only viable option, as the MI355X cannot output video. For compute workloads, the MI355X's 288 GB of HBM3e and 8.19 TB/s of bandwidth, combined with 78.64 TFLOPS of FP32, indicate a far more capable accelerator on paper. The RX 9060 XT LP's 16 GB of GDDR6 and 24.99 TFLOPS are a fraction of those figures.

The RX 9060 XT LP's measured benchmark scores place it in the 89th percentile of all GPUs, with competitive results against the NVIDIA CMP 30HX and AMD Radeon RX 7600M. The MI355X has no benchmark data, so its percentile of 50 is not a meaningful performance indicator. The data supports selecting the RX 9060 XT LP for any graphics-focused build and the MI355X for dedicated compute installations where its power and cooling requirements can be met.

Where Each One Wins

The MI355X wins decisively in compute density. Its 16384 shading units dwarf the RX 9060 XT LP's 2048, and its 1024 TMUs compare to 128. The texture rate of 2,457.6 GTexel/s is over six times the RX 9060 XT LP's 390.4 GTexel/s. The MI355X's 288 GB memory capacity allows handling datasets that would be impossible on the RX 9060 XT LP's 16 GB. The 8.19 TB/s bandwidth is unmatched by the RX 9060 XT LP's 322.3 GB/s, making the MI355X suited for memory-bound workloads.

The RX 9060 XT LP wins in graphics features. It has 64 ROPs and 32 ray tracing cores, while the MI355X has zero ROPs and no ray tracing cores. The RX 9060 XT LP supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI355X lists N/A for all APIs. The RX 9060 XT LP's pixel rate of 195.2 GPixel/s is achievable, whereas the MI355X's pixel rate is 0 MPixel/s. The RX 9060 XT LP also has display outputs, making it the only choice for visual output.

The RX 9060 XT LP wins on efficiency and practicality. Its 140 W TDP with a 300 W suggested PSU contrasts with the MI355X's 1400 W TDP and 1800 W suggested PSU. The RX 9060 XT LP is a dual-slot card with a single 8-pin connector, while the MI355X is an OAM module with no power connectors, requiring a specialized chassis. The RX 9060 XT LP's higher clocks, 3050 MHz boost versus 2400 MHz, benefit latency-sensitive workloads.

The MI355X wins on memory technology. HBM3e offers far higher bandwidth per watt than GDDR6, and the 8192-bit bus is a class of its own. The 185,000 million transistors on a 2380 mm² die indicate a part built for maximum compute throughput, not for efficiency or cost. The RX 9060 XT LP's 29,700 million transistors on 199 mm² show a more modest, focused design.
