AMD Instinct MI355X vs AMD Radeon RX 7600M Comparison

Head-to-Head Benchmarks

The recorded data contains a single benchmark entry for the AMD Radeon RX 7600M, while the AMD Instinct MI355X has no benchmark scores listed. This makes a direct numerical comparison impossible in most workloads. The only measurable result is the RX 7600M's Geekbench OpenCL score of 63,775, which places it in the 89th percentile among all GPUs in the database. Against its nearest rivals, the RX 7600M sits within a narrow band: it trails the AMD Radeon RX 9060 XT LP by 0.1% (that card scores 63,830), trails the NVIDIA CMP 30HX by 0.1% (63,842), leads the AMD Radeon Pro Vega 56 by 0.1% (63,693), and trails the AMD Radeon Pro WX 9100 by 0.7% (64,212). The MI355X, by contrast, holds a 50th percentile ranking with an average benchmark score of zero, indicating no recorded results in this database.

The MI355X does, however, present massive theoretical compute figures that dwarf the RX 7600M's measured output. The MI355X delivers 78.64 TFLOPS of FP32 performance, while the RX 7600M delivers 17.27 TFLOPS. That is a 4.55x advantage in raw single-precision throughput for the Instinct part. In FP16, the gap widens further: the MI355X provides 78.64 TFLOPS at a 1:1 ratio, whereas the RX 7600M provides 34.55 TFLOPS at a 2:1 ratio. The texture rate tells a similar story, with the MI355X at 2,457.6 GTexel/s versus 269.9 GTexel/s for the RX 7600M, a 9.1x difference. The pixel rate, however, is inverted: the RX 7600M produces 154.2 GPixel/s, while the MI355X is listed at 0 MPixel/s, reflecting its lack of ROPs and display output capability.

Memory bandwidth is another area of overwhelming divergence. The MI355X uses 288 GB of HBM3e across an 8192-bit bus, yielding 8.19 TB/s. The RX 7600M uses 8 GB of GDDR6 across a 128-bit bus, yielding 256.0 GB/s. The Instinct card offers 32 times the bandwidth. The MI355X's transistor count of 185,000 million and die size of 2380 mm² on a 3 nm TSMC process stand against the RX 7600M's 13,300 million transistors and 204 mm² die on a 6 nm process. The MI355X also has 16,384 shading units and 1,024 TMUs, versus 1,792 shading units and 112 TMUs for the RX 7600M.

Where Each One Wins

The RX 7600M is the only one of the two with any recorded benchmark score, so it is the clear winner in measured, real-world database results. Its Geekbench OpenCL score of 63,775 places it in the 89th percentile, and its nearest rival comparisons show it trading blows with cards like the RX 9060 XT LP and NVIDIA CMP 30HX, both within 0.1%. The RX 7600M also has a functional pixel pipeline with 64 ROPs, a pixel rate of 154.2 GPixel/s, and 28 ray tracing cores. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, making it applicable to gaming and general graphics workloads. Its 8 GB of GDDR6 memory and 256.0 GB/s bandwidth are modest but sufficient for its mobile, integrated graphics processor (IGP) form factor, and its 90 W TDP indicates a low-power design.

The MI355X wins decisively in raw compute capability, but that advantage is theoretical because no benchmark scores exist for it in the database. Its 78.64 TFLOPS FP32 and FP16 (1:1) figures, 8.19 TB/s memory bandwidth, 288 GB capacity, and 16,384 shading units position it as a data center or HPC accelerator. It has no ROPs, no pixel rate, no display outputs, and no DirectX, OpenGL, or Vulkan support, so it cannot function in a graphics rendering role. Its 1400 W TDP and OAM module slot width indicate a server-oriented design, not a portable one. The MI355X also has no ray tracing cores listed and no tensor cores listed, so its architecture is specialized for compute rather than graphics or AI inference as measured by standard GPU benchmarks.

The Verdict

The data indicates that these two products serve entirely different purposes, and the choice between them depends on the workload. For any task that involves rendering, display output, or consumer graphics, the RX 7600M is the only viable option. It has a benchmark score, a full graphics API stack, 64 ROPs, 28 ray tracing cores, and a 90 W power envelope that suits a portable device. Its 89th percentile ranking and near-parity with the RX 9060 XT LP and NVIDIA CMP 30HX (both within 0.1%) show that it is a competitive mobile GPU. The MI355X cannot be used for such tasks because it has no display outputs and no graphics API support.

For pure compute workloads, the MI355X is the clear choice based on specifications. Its 78.64 TFLOPS FP32 is more than four times the RX 7600M's 17.27 TFLOPS, and its 8.19 TB/s memory bandwidth is 32 times higher. The 288 GB memory capacity is 36 times larger than the 8 GB on the RX 7600M. However, the absence of any benchmark score for the MI355X means the database cannot confirm how that theoretical performance translates into real applications. The RX 7600M, with its measured 63,775 OpenCL score, is the only one with verified performance data. A buyer needing a working GPU today, with proven results, would select the RX 7600M. A buyer with a compute server and a workload that can use HBM3e memory and massive FP32 throughput would select the MI355X, accepting that its performance is unverified in this database.
