AMD Instinct MI325X vs AMD Radeon RX 7600S Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Instinct MI325X versus the AMD Radeon RX 7600S. The Instinct MI325X has no recorded benchmark scores, an average benchmark score of zero, and a percentile rank of 50 among all GPUs. The RX 7600S, by contrast, carries ten individual benchmark scores across DirectX, OpenCL, Vulkan, and Passmark tests, with an average benchmark score of 16,696 and a percentile rank of 60.

Because the Instinct MI325X lacks any measured performance data, the comparison rests entirely on the RX 7600S's recorded results and the architectural specifications of both parts. The RX 7600S's strongest recorded result appears in Geekbench Vulkan with a score of 73,868, followed closely by Geekbench OpenCL at 68,012. Its Passmark G3D score of 15,408 places it in the same performance vicinity as several NVIDIA workstation and mobile parts. The nearest rivals in the database include the NVIDIA T400 4 GB with an average score of 16,792 and a delta of -0.6 percent, meaning the RX 7600S trails that card by less than one percent. The NVIDIA T400 scores 16,508, putting the RX 7600S 1.1 percent ahead. The NVIDIA GeForce RTX 5090 D V2 scores 16,504, again with the RX 7600S ahead by 1.2 percent. The NVIDIA Tesla M4 scores 16,932, placing the RX 7600S 1.4 percent behind.

The RX 7600S's Passmark DirectX 9 score of 211 exceeds its DirectX 11 score of 140, its DirectX 10 score of 74, and its DirectX 12 score of 65. This pattern indicates the mobile part performs relatively better on legacy DirectX workloads than on modern API paths, though the Passmark G3D composite of 15,408 and the GPU compute score of 6,520 provide broader context. The Geekbench OpenCL and Vulkan scores both exceed 68,000, suggesting strong compute and graphics throughput for a 75 W mobile GPU.

For the Instinct MI325X, the absence of benchmark data means no wins can be recorded from measured tests. The head-to-head benchmark count between the two parts is zero, and the wins tally shows zero for each side. Any performance comparison must therefore rely on theoretical specifications rather than empirical results.

Architecture Differences

The two AMD GPUs diverge fundamentally in architecture, process technology, and intended role. The Instinct MI325X uses the Aqua Vanjaram chip built on CDNA 3.0 architecture, fabricated on a 5 nm process at TSMC. It belongs to the Instinct (MIx) generation and carries 153,000 million transistors across a 1017 mm² die. The RX 7600S uses the Navi 33 chip built on RDNA 3.0 architecture, fabricated on a 6 nm process at TSMC. It belongs to the Navi Mobile (RX 7000M) generation with the codename Hotpink Bonefish, and carries 13,300 million transistors across a 204 mm² die.

The transistor density gap is substantial: the MI325X packs 150.4 million transistors per square millimeter, while the RX 7600S manages 65.2 million. This density difference reflects the 5 nm versus 6 nm process gap and the fundamentally different design goals. The MI325X is a compute accelerator with 19,456 shading units, 1,216 texture mapping units, and zero raster operation units. Its pixel rate is listed as 0 MPixel/s, confirming it is not designed for rasterized graphics output. The RX 7600S, by contrast, has 1,792 shading units, 112 TMUs, 64 ROPs, and 28 ray tracing cores, with a pixel rate of 140.8 GPixel/s.

Memory architecture differs completely. The MI325X uses 256 GB of HBM3e across an 8192-bit bus, delivering 6.14 TB/s of bandwidth. The RX 7600S uses 8 GB of GDDR6 across a 128-bit bus, delivering 256.0 GB/s of bandwidth. Clock behavior also differs: the MI325X has a 1000 MHz base and 2100 MHz boost, while the RX 7600S has a 1500 MHz base, 1865 MHz game clock, and 2200 MHz boost. The MI325X's memory clock is 1500 MHz with 6 Gbps effective, while the RX 7600S's memory clock is 2000 MHz with 16 Gbps effective.

The MI325X has no display outputs, no power connectors, and uses an OAM Module slot width. The RX 7600S is an IGP with display outputs described as portable device dependent. The MI325X uses PCIe 5.0 x16, while the RX 7600S uses PCIe 4.0 x16. The MI325X's TDP is 1000 W with a suggested PSU of 1400 W. The RX 7600S's TDP is 75 W with no suggested PSU listed. The MI325X lists N/A for all graphics APIs, while the RX 7600S supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates two entirely different product categories. The Instinct MI325X is a data center accelerator with no benchmark scores, no display outputs, no graphics API support, and a 1000 W TDP. The RX 7600S is a mobile graphics processor with active production status, ten benchmark scores, full API support, and a 75 W TDP.

For compute throughput based on specifications, the MI325X delivers 81.72 TFLOPS FP32 and 81.72 TFLOPS FP16 (1:1 ratio). The RX 7600S delivers 15.77 TFLOPS FP32 and 31.54 TFLOPS FP16 (2:1 ratio). The MI325X's texture rate is 2,553.6 GTexel/s versus the RX 7600S's 246.4 GTexel/s. These figures show the MI325X exceeds the RX 7600S by roughly five times in FP32 throughput and by more than ten times in texture rate, though neither has direct head-to-head benchmark confirmation.

The RX 7600S, however, is the only one of the two with measured performance. Its percentile rank of 60 places it above the MI325X's rank of 50, and its average benchmark score of 16,696 stands against the MI325X's zero. For any workload requiring graphics output, DirectX, OpenGL, or Vulkan support, the MI325X is inapplicable. For any workload requiring HBM3e memory capacity of 256 GB, the RX 7600S's 8 GB GDDR6 allocation is insufficient.

The verdict depends on the workload class. The data supports the MI325X for large-scale compute tasks where 256 GB of HBM3e, an 8192-bit bus, and 6.14 TB/s bandwidth are necessary, and where the absence of display outputs and graphics APIs is irrelevant. The RX 7600S is the appropriate choice for mobile graphics and compute workloads that require DirectX 12 Ultimate, OpenGL 4.6, or Vulkan 1.4 support, and where power consumption must remain at 75 W.

Where Each One Wins

The Instinct MI325X wins in every specification category tied to raw compute scale. Its 256 GB HBM3e memory dwarfs the RX 7600S's 8 GB GDDR6, and its 6.14 TB/s bandwidth is 24 times the RX 7600S's 256.0 GB/s. The 8192-bit memory bus versus 128-bit gives the MI325X a massive memory parallelism advantage. The MI325X's 81.72 TFLOPS FP32 and FP16 throughput exceeds the RX 7600S's 15.77 TFLOPS FP32 and 31.54 TFLOPS FP16. The MI325X's 2,553.6 GTexel/s texture rate is more than ten times the RX 7600S's 246.4 GTexel/s. The MI325X also benefits from PCIe 5.0 x16 versus PCIe 4.0 x16, a 5 nm process versus 6 nm, and a much higher transistor density. Its release date of 2024-10-09 is newer than the RX 7600S's 2023-01-03. For data center compute, the MI325X is the clear specification leader.

The RX 7600S wins in every category related to graphics functionality and measured performance. It has 64 ROPs and 28 ray tracing cores, while the MI325X has 0 ROPs and no ray tracing cores. The RX 7600S's pixel rate of 140.8 GPixel/s stands against the MI325X's 0 MPixel/s. The RX 7600S supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the MI325X lists N/A for all three APIs. The RX 7600S has display outputs, the MI325X has none. The RX 7600S's 75 W TDP is dramatically lower than the MI325X's 1000 W TDP, and it requires no suggested PSU while the MI325X specifies 1400 W. The RX 7600S has an active production status, while the MI325X's is not listed. The RX 7600S also holds a higher percentile rank of 60 versus 50, and its average benchmark score of 16,696 far exceeds the MI325X's zero. For mobile graphics, gaming, and any application requiring display output or graphics APIs, the RX 7600S is the only viable option between the two.
