Architecture Differences

The AMD Instinct MI355X and AMD Radeon 760M represent two distinct architectural philosophies from the same manufacturer. The MI355X is built on CDNA 4.0, a compute-optimized architecture designed for data center acceleration, while the 760M uses RDNA 3.0, a graphics-oriented architecture for integrated solutions.

The manufacturing processes differ significantly. The MI355X uses a 3 nm process at TSMC with 185,000 million transistors on a 2380 mm² die, resulting in a transistor density of 77.7M per mm². The 760M uses a 4 nm process at the same foundry with 25,390 million transistors on a 178 mm² die, achieving a higher transistor density of 142.6M per mm². The MI355X die is over 13 times larger in area, but the 760M packs transistors more densely.

Compute resources diverge sharply. The MI355X contains 16,384 shading units and 1,024 texture mapping units, with no ROPs recorded. The 760M has 512 shading units, 32 TMUs, and 16 ROPs, plus 8 ray tracing cores. The MI355X does not list ray tracing cores in the database. The MI355X pixel rate is 0 MPixel/s, reflecting its lack of rasterization hardware, while the 760M delivers 41.58 GPixel/s.

Clock behavior differs as well. The MI355X runs at a base clock of 1000 MHz and boosts to 2400 MHz. The 760M starts at 800 MHz base and boosts higher to 2599 MHz. Despite the lower base clock, the 760M achieves a higher boost frequency, though its raw throughput is far smaller.

Memory architecture separates these products completely. The MI355X uses 288 GB of HBM3e on a 8192-bit bus with 8.19 TB/s bandwidth. The 760M relies on System Shared memory, where size, type, bus width, and bandwidth are all system dependent. The MI355X memory runs at 2000 MHz with 8 Gbps effective data rate.

The bus interface differs: the MI355X uses PCIe 5.0 x16, while the 760M uses PCIe 4.0 x8. The MI355X has no display outputs, while the 760M outputs are motherboard dependent. The MI355X measures 102 mm in length and 165 mm in width, while the 760M has no recorded dimensions.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the Instinct MI355X and the Radeon 760M. The MI355X has an empty benchmark array, an average benchmark score of 0, and a percentile versus all GPUs of 50. The 760M has recorded benchmarks across multiple tests with an average score of 6,019 and a percentile of 35.

The MI355X cannot be benchmarked through standard graphics tests because it lacks DirectX, OpenGL, and Vulkan API support. The 760M shows capability in graphics workloads with a Passmark G3D score of 5,310 and a Passmark G2D score of 890. Its compute performance appears in Geekbench OpenCL at 20,255 and Geekbench Vulkan at 30,336.

The 760M nearest rivals provide context for its performance level. It sits 0.3% above the AMD Radeon RX 6400 and NVIDIA GeForce GTX 770M, both scoring 6,001 and 6,000 respectively. It is 0.4% above the NVIDIA RTX PRO 6000 Blackwell Server at 5,996. Against the NVIDIA Quadro P2000 at 6,049, the 760M trails by 0.5%.

For the MI355X, the lack of benchmark data means no comparative analysis is possible from the recorded information. Its percentile of 50 with zero average score indicates no measured performance data exists in the database.

The texture and pixel rates show the compute focus of each product. The MI355X delivers 2,457.6 GTexel/s texture rate with 0 MPixel/s pixel rate. The 760M delivers 83.17 GTexel/s texture rate and 41.58 GPixel/s pixel rate. These numbers confirm the MI355X is not designed for rasterization output.

Floating point performance reveals the compute gap. The MI355X achieves 78.64 TFLOPS for both FP32 and FP16 (1:1 ratio). The 760M achieves 5.323 TFLOPS for both FP32 and FP16 (1:1 ratio). The MI355X delivers approximately 14.8 times the FP32 throughput based on these recorded figures.

Where Each One Wins

The Instinct MI355X wins decisively in compute throughput. Its 78.64 TFLOPS FP32 and FP16 performance dwarfs the 760M's 5.323 TFLOPS. The texture rate of 2,457.6 GTexel/s exceeds the 760M's 83.17 GTexel/s by a wide margin. The 288 GB HBM3e memory with 8.19 TB/s bandwidth provides massive capacity and bandwidth for large data sets, far beyond the system shared memory of the 760M.

The MI355X also wins in process technology with the 3 nm node versus 4 nm, and in bus interface with PCIe 5.0 x16 versus PCIe 4.0 x8. The larger die size at 2380 mm² versus 178 mm² allows for significantly more compute resources.

The Radeon 760M wins in graphics-specific features. It supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI355X has no graphics API support. The 760M delivers 41.58 GPixel/s pixel rate, while the MI355X delivers 0 MPixel/s. The 8 ray tracing cores in the 760M enable ray-traced workloads that the MI355X cannot handle.

The 760M wins in power efficiency. Its 15 W TDP is dramatically lower than the 1400 W TDP of the MI355X, requiring no suggested power supply. The 760M also achieves a higher boost clock at 2599 MHz versus 2400 MHz, and a higher transistor density at 142.6M per mm² versus 77.7M per mm².

The 760M has recorded benchmark scores including 5,310 in Passmark G3D and 30,336 in Geekbench Vulkan, while the MI355X has no benchmark data. The 760M production status is Active, while the MI355X has no production status recorded. The 760M has a defined average benchmark score of 6,019, whereas the MI355X average is 0.

The Verdict

The database shows two AMD products with essentially no overlap in purpose. The Instinct MI355X is a data center compute accelerator with 78.64 TFLOPS FP32, 288 GB HBM3e memory, and no graphics output capability. The Radeon 760M is an integrated graphics processor with 5.323 TFLOPS FP32, system shared memory, and full graphics API support.

The MI355X is for compute-only workloads that require massive memory capacity and bandwidth. Its 8.19 TB/s memory bandwidth and 2,457.6 GTexel/s texture rate support large-scale parallel processing. Its 1400 W TDP and 1800 W suggested PSU indicate a server-class deployment. The lack of display outputs and graphics APIs confirms its role as an accelerator rather than a graphics card.

The 760M is for graphics rendering and display output in integrated systems. Its DirectX 12 Ultimate support, OpenGL 4.6, and Vulkan 1.4 enable gaming and graphics applications. The 41.58 GPixel/s pixel rate and 16 ROPs provide rasterization capability. Its 8 ray tracing cores support ray-traced effects. The 15 W TDP fits within power-constrained mobile or compact desktop designs.

The benchmark data shows the 760M performing close to its nearest rivals: 0.3% above the RX 6400 and GTX 770M, 0.4% above the RTX PRO 6000 Blackwell Server, and 0.5% below the Quadro P2000. The MI355X has no comparable benchmark scores, so its performance relative to other GPUs cannot be assessed from the database.

The release dates show the 760M launched earlier on 2024-01-30, with the MI355X following on 2025-06-11. Both products share the AMD manufacturer, but their architectures serve different markets. CDNA 4.0 targets compute acceleration, while RDNA 3.0 targets graphics processing.

The verdict from the data is clear: the MI355X wins for compute-heavy data center workloads requiring high FP32 throughput and large memory pools. The 760M wins for graphics rendering, API compatibility, and low-power integrated solutions. Neither product can substitute for the other in their respective domains.
