AMD Radeon 8040S vs AMD Radeon RX 7650 GRE Comparison

Head-to-Head Benchmarks

The benchmark database shows two GPUs at opposite ends of the performance spectrum. The AMD Radeon RX 7650 GRE posts an average benchmark score of 42,723, while the AMD Radeon 8040S averages just 2,440. That is a 40,283 point gap, or roughly 17.5 times the integrated part's score. The RX 7650 GRE sits in the 83rd percentile of all GPUs tracked, while the 8040S lands in the 17th percentile.

In DirectX workloads, the RX 7650 GRE delivers a Geekbench OpenCL score of 83,109 and a 3DMark Steel Nomad DX12 score of 2,336. The 8040S has no comparable 3DMark or Geekbench entries in the database, but its Passmark suite shows the limits of the integrated design. The 8040S scores 134 in Passmark DirectX 9, 80 in DirectX 11, 48 in DirectX 10, and 47 in DirectX 12. Its best result comes in Passmark G3D with 10,578, a figure that still trails the discrete card's average benchmark by roughly a factor of four.

The RX 7650 GRE's nearest rivals in the database are the NVIDIA GeForce RTX 4070 SUPER (average score 43,223, delta -1.2%), the NVIDIA Quadro M6000 24 GB (43,262, -1.2%), and the NVIDIA GeForce RTX 5050 Mobile (43,268, -1.3%). The 8040S, by contrast, sits closest to the NVIDIA GeForce 710M (2,433, +0.3%), Intel HD Graphics 610 (2,425, +0.6%), and NVIDIA GeForce GT 710M (2,422, +0.7%). The 8040S edges out the AMD Radeon RX 7400 by 1.1%, but that rival's average of 2,467 is still higher than the 8040S's 2,440.

The compute gap is equally stark. The RX 7650 GRE delivers 22.08 TFLOPS FP32, while the 8040S manages 5.734 TFLOPS. In pixel throughput, the discrete card hits 172.5 GPixel/s versus 89.60 GPixel/s for the integrated part. Texture rate shows a similar pattern: 345.0 GTexel/s for the RX 7650 GRE, 179.2 GTexel/s for the 8040S. The 8040S's Passmark GPU compute score of 5,138 does not approach the RX 7650 GRE's OpenCL result of 83,109, though the different test suites make a direct comparison less precise.

Architecture Differences

The two GPUs come from different generations of AMD's RDNA architecture. The AMD Radeon 8040S uses RDNA 3.5 on the Strix Halo chip, built on TSMC's 4 nm process. The RX 7650 GRE uses RDNA 3.0 on the Navi 33 chip, codenamed Hotpink Bonefish, manufactured on a 6 nm TSMC node. The die sizes reflect the different designs: the 8040S measures 308 mm², while the RX 7650 GRE measures 204 mm². The RX 7650 GRE's transistor count is listed as 13,300 million with a density of 65.2M per mm²; the 8040S's transistor count is listed as unknown.

The RX 7650 GRE's compute configuration is exactly double the 8040S in most respects. The discrete card has 2,048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. The 8040S has 1,024 shading units, 64 TMUs, 32 ROPs, and 16 ray tracing cores. Memory architecture differs fundamentally. The RX 7650 GRE uses 8 GB of GDDR6 on a 128 bit bus with 288.0 GB/s bandwidth and memory clocks at 2250 MHz (18 Gbps effective). The 8040S uses system shared memory with a system dependent bus width and bandwidth, so its memory performance scales with the host platform rather than a dedicated VRAM pool.

Clock behavior also separates the two. The RX 7650 GRE runs a base clock of 1720 MHz, a game clock of 2350 MHz, and a boost clock of 2695 MHz. The 8040S runs a lower base of 1295 MHz but a higher boost of 2800 MHz. Power draw is a major differentiator: the RX 7650 GRE has a 170 W TDP with a 1x 8-pin power connector and a suggested PSU of 450 W, while the 8040S is rated at 55 W as an integrated graphics processor with no power connectors. The RX 7650 GRE is a dual-slot card measuring 204 mm by 115 mm, whereas the 8040S is an IGP with dimensions dependent on the portable device.

The RX 7650 GRE uses PCIe 4.0 x8 and offers 1x HDMI 2.1a plus 3x DisplayPort 2.1 outputs. The 8040S uses PCIe 5.0 x16 with display outputs described as portable device dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7650 GRE is part of the Radeon RX 7000 series within the Navi III generation, succeeding Navi II and preceding Navi IV. The 8040S belongs to the Navi Mobile (RX 8000M) generation, with its predecessor listed as Polaris Mobile.

The Verdict

The data separates these two GPUs cleanly by role. The AMD Radeon RX 7650 GRE is a discrete, dual-slot desktop card with 8 GB of dedicated GDDR6 memory, 2,048 shading units, and 22.08 TFLOPS FP32. Its average benchmark score of 42,723 places it within 1.3% of the NVIDIA GeForce RTX 4070 SUPER, the Quadro M6000 24 GB, and the GeForce RTX 5050 Mobile. The 83rd percentile ranking confirms it as a mid-to-high tier performer in the database.

The AMD Radeon 8040S is an integrated graphics processor with 1,024 shading units, system shared memory, and a 55 W TDP. Its 2,440 average score and 17th percentile placement put it in the same performance band as the NVIDIA GeForce 710M and Intel HD Graphics 610. The 8040S's only database rival it beats is the AMD Radeon RX 7400, by 1.1%, and that rival still scores higher in absolute terms.

For workloads requiring sustained frame rates, high resolution textures, or compute throughput, the recorded data points to the RX 7650 GRE. Its 288.0 GB/s of dedicated bandwidth, 64 ROPs, and 32 ray tracing cores give it resources the 8040S cannot match. The 8040S suits systems where power draw and integration matter more than raw performance. Its 55 W TDP, lack of external power connectors, and PCIe 5.0 x16 interface make it a low-power option for portable devices, but the benchmark results show it operates in a different performance class. The RX 7650 GRE's 170 W TDP and 450 W suggested PSU reflect the cost of its 40,283 point average score advantage.
