Architecture Differences

The two GPUs come from fundamentally different architectural eras and design philosophies. The NVIDIA Tesla P40 uses the GP102 chip built on the Pascal architecture, fabricated on a 16 nm TSMC process. The RX 7600M uses the Navi 33 chip with the RDNA 3.0 architecture, built on a 6 nm TSMC process.

The process node difference is stark: 16 nm versus 6 nm. This directly impacts transistor density. The Tesla P40 packs 11,800 million transistors over a 471 mm² die, yielding a density of 25.1M transistors per mm². The RX 7600M contains 13,300 million transistors over a much smaller 204 mm² die, achieving a density of 65.2M per mm² — over 2.5 times denser.

The compute architectures diverge significantly. The Tesla P40 has 3,840 shading units, 240 texture mapping units, and 96 ROPs. The RX 7600M has 1,792 shading units, 112 TMUs, and 64 ROPs. The NVIDIA card has no ray tracing cores or tensor cores listed; the AMD card has 28 ray tracing cores.

The memory subsystems also differ fundamentally. The P40 uses 24 GB of GDDR5 on a 384-bit bus, delivering 347.1 GB/s of bandwidth. The RX 7600M uses 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s. The P40’s memory clock is 1808 MHz (7.2 Gbps effective), while the RX 7600M’s is 2000 MHz (16 Gbps effective).

The NVIDIA card is a dual-slot PCIe 3.0 x16 accelerator with no display outputs, drawing 250 W via an 8-pin EPS connector. The AMD card is an IGP (integrated graphics package) with no dedicated power connectors, drawing 90 W, and its display outputs are portable device dependent. The RX 7600M uses PCIe 4.0 x16.

The FP16 capabilities are dramatically different. The P40 manages only 183.7 GFLOPS (1:64 ratio), while the RX 7600M hits 34.55 TFLOPS (2:1 ratio). The AMD card also supports DirectX 12 Ultimate (12_2), whereas the NVIDIA card supports DirectX 12 (12_1).

Head-to-Head Benchmarks

The only direct benchmark comparison available is Geekbench OpenCL, and the data is close. The AMD Radeon RX 7600M scored 63,775 against the NVIDIA Tesla P40’s 62,017. This yields a delta of -2.8% from the P40’s perspective, meaning the AMD card is 2.8% faster.

Despite the narrow margin, the context matters. The P40’s average benchmark score across all tests is 65,095, which is higher than its OpenCL-only score. The RX 7600M’s average benchmark score is 63,775, identical to its OpenCL score since that is the only benchmark recorded. This suggests the P40 performs relatively better in other workloads, though no additional head-to-head data is provided.

Looking at the nearest rivals for each card clarifies the competitive landscape. The P40 sits between the Radeon Pro WX 9100 (64,212) and the Radeon VII (66,004). The RX 7600M sits within 0.7% of three different rivals: the RX 9060 XT LP (63,830), CMP 30HX (63,842), and Radeon Pro Vega 56 (63,693). This shows the RX 7600M is tightly clustered with its peers, while the P40 has a slightly wider spread.

The transistor and clock differences explain part of the performance picture. The RX 7600M has a base clock of 1500 MHz and a boost clock of 2410 MHz, with a game clock of 2070 MHz. The P40’s base clock is 1303 MHz and boost is 1531 MHz. The AMD card’s higher clocks, despite fewer shading units, contribute to its higher FP32 throughput of 17.27 TFLOPS versus 11.76 TFLOPS.

The pixel rates are nearly identical: 154.2 GPixel/s for the RX 7600M versus 147.0 GPixel/s for the P40. The texture rates differ more substantially, with the P40 at 367.4 GTexel/s versus 269.9 GTexel/s for the AMD card. This indicates the NVIDIA card has a strength in texture-heavy workloads despite losing the compute race.

The Verdict

The data presents a split verdict. For raw compute throughput, the AMD Radeon RX 7600M is the clear winner. Its FP32 rating of 17.27 TFLOPS exceeds the Tesla P40’s 11.76 TFLOPS by a wide margin. The AMD card also wins the only direct benchmark, the Geekbench OpenCL test, by 2.8%. Additionally, the RX 7600M offers modern features the P40 lacks: 28 ray tracing cores, DirectX 12 Ultimate support, and FP16 performance at a 2:1 ratio (34.55 TFLOPS versus 183.7 GFLOPS).

For memory capacity and bandwidth, the NVIDIA Tesla P40 dominates. It offers 24 GB of VRAM versus 8 GB, a 384-bit bus versus 128-bit, and 347.1 GB/s of bandwidth versus 256.0 GB/s. The P40 also has a higher texture rate (367.4 GTexel/s versus 269.9 GTexel/s). These characteristics make the P40 better suited for workloads that require large datasets in memory or heavy texture sampling.

The power profiles are entirely different. The P40 is a 250 W dual-slot accelerator requiring an 8-pin EPS connector and a 600 W suggested PSU. The RX 7600M is a 90 W IGP with no power connectors. For mobile or power-constrained systems, the RX 7600M is the only viable option. For a workstation with ample power and space, the P40’s higher memory capacity is the differentiator.

The architecture age also matters. The P40 is end-of-life, released in September 2016, and belongs to the Tesla Pascal generation. The RX 7600M is active, released in January 2023, and belongs to the Navi Mobile (RX 7000M) generation. Buyers seeking long-term driver support and modern API features should favor the AMD card. The P40’s era is reflected in its PCIe 3.0 interface versus PCIe 4.0 on the RX 7600M.

The benchmark percentile ranking shows both at the 89th percentile, suggesting comparable overall standing despite the architectural differences. The P40’s average score of 65,095 is actually higher than the RX 7600M’s 63,775, which may reflect the P40’s strength in other tests not covered in the head-to-head data. However, only the OpenCL test provides a direct comparison, and the AMD card wins that one.
