The 680M, by contrast, sits in the 57th percentile with an average benchmark score of 15270. Its nearest rivals are the NVIDIA GeForce GTX 580 at 15283 (0.1 percent ahead), the NVIDIA GeForce RTX 2060 at 15290 (0.1 percent ahead), and the NVIDIA GeForce RTX 3050 OEM at 15199 (0.5 percent behind). The AMD Radeon RX 7600 scores 15171, putting it 0.7 percent behind the 680M in the database's average score calculation. This places the 680M in the middle of the GPU performance distribution, suitable for lighter workloads but far from the top tier.

For use cases, the RX 7650 GRE is the clear choice for any application requiring substantial graphics throughput, such as modern gaming or GPU-accelerated compute. The 680M, with its system-shared memory and 50 W TDP, fits portable devices where power draw is constrained and performance requirements are modest.

Architecture Differences

The two GPUs come from different architecture generations. The AMD Radeon 680M uses RDNA 2.0 architecture with the Rembrandt+ chip, while the AMD Radeon RX 7650 GRE uses RDNA 3.0 architecture with the Navi 33 chip, codenamed Hotpink Bonefish. The 680M is from the Navi II IGP generation, whereas the RX 7650 GRE belongs to the Navi III (RX 7000) series.

Both GPUs are manufactured on a 6 nm process at TSMC. The 680M has 13,100 million transistors on a 208 mm² die, giving a transistor density of 63.0 million per square millimeter. The RX 7650 GRE has 13,300 million transistors on a 204 mm² die, resulting in a density of 65.2 million per square millimeter. The transistor counts are close, but the architectural differences are significant.

The 680M features 768 shading units, 48 texture mapping units, 32 render output units, and 12 ray tracing cores. The RX 7650 GRE uses 2048 shading units, 128 TMUs, 64 ROPs, and 32 ray tracing cores. This represents a 2.7x increase in shading units, a 2.7x increase in TMUs, a 2x increase in ROPs, and a 2.7x increase in ray tracing cores.

Clock speeds show a different pattern. The 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz. The RX 7650 GRE has a lower base clock of 1720 MHz but a much higher boost clock of 2695 MHz, with a game clock of 2350 MHz. The memory clock on the RX 7650 GRE is 2250 MHz with 18 Gbps effective data rate.

The 680M uses system-shared memory, meaning its memory size, type, bus width, and bandwidth are all dependent on the host system. The RX 7650 GRE has dedicated 8 GB of GDDR6 memory on a 128-bit bus, providing 288.0 GB/s of bandwidth. This dedicated memory arrangement is a fundamental advantage for the discrete card.

Pixel rate on the 680M is 70.40 GPixel/s, while the RX 7650 GRE achieves 172.5 GPixel/s. Texture rate is 105.6 GTexel/s for the 680M and 345.0 GTexel/s for the RX 7650 GRE. FP32 performance is 3.379 TFLOPS for the 680M and 22.08 TFLOPS for the RX 7650 GRE, a 6.5x difference. FP16 performance is 6.758 TFLOPS for the 680M (with a 2:1 ratio) and 22.08 TFLOPS for the RX 7650 GRE (with a 1:1 ratio).

Power consumption differs substantially. The 680M has a TDP of 50 W and uses no power connectors, being an IGP. The RX 7650 GRE has a TDP of 170 W, requires a single 8-pin power connector, and needs a suggested PSU of 450 W. The 680M is an IGP slot width, while the RX 7650 GRE is a dual-slot card measuring 204 mm in length and 115 mm in height.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The bus interface is PCIe 4.0 x8 for both. The 680M's display outputs are listed as portable device dependent, while the RX 7650 GRE has 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs.

Head-to-Head Benchmarks

The database records two head-to-head benchmark comparisons, and the RX 7650 GRE wins both. In the 3DMark Steel Nomad DX12 test, the RX 7650 GRE scores 2336 against the 680M's 378. The delta percentage is -83.8, meaning the 680M's score is 83.8 percent lower than the RX 7650 GRE's score. This is a massive gap, indicating that the discrete card delivers over six times the performance in this synthetic DirectX 12 workload.

In the Geekbench OpenCL test, the RX 7650 GRE scores 83109 against the 680M's 23468. The delta percentage is -71.8, meaning the 680M's score is 71.8 percent lower. This test measures general-purpose compute performance through the OpenCL API, and the RX 7650 GRE's 2048 shading units and 22.08 TFLOPS FP32 performance provide a decisive advantage over the 680M's 768 shading units and 3.379 TFLOPS.

The average benchmark score for the RX 7650 GRE is 42723, compared to 15270 for the 680M. The RX 7650 GRE's nearest rival, the NVIDIA GeForce RTX 4070 SUPER, scores 43223, which is 1.2 percent higher. The 680M's nearest rival, the NVIDIA GeForce GTX 580, scores 15283, which is 0.1 percent higher. The RX 7650 GRE holds a 179.8 percent higher average score than the 680M, placing them in completely different performance brackets.

The percentile rankings confirm this divide. The RX 7650 GRE sits in the 83rd percentile of all GPUs, while the 680M sits in the 57th percentile. This means the RX 7650 GRE outperforms the vast majority of GPUs in the database, while the 680M sits just above the median.

The Verdict

The recorded data shows that the AMD Radeon RX 7650 GRE is the overwhelmingly faster GPU in every measured benchmark. Its average benchmark score of 42723 is nearly three times the 680M's 15270. The 3DMark Steel Nomad DX12 score of 2336 versus 378 and the Geekbench OpenCL score of 83109 versus 23468 demonstrate a performance gap of over 70 percent in both tests.

The RX 7650 GRE is appropriate for users who need dedicated graphics performance with 8 GB of GDDR6 memory, 288.0 GB/s bandwidth, and 22.08 TFLOPS of FP32 compute. Its 83rd percentile ranking places it alongside the NVIDIA GeForce RTX 4070 SUPER, which scores only 1.2 percent higher on average. The 170 W TDP and dual-slot design indicate it is meant for desktop systems with a 450 W PSU.

The 680M serves a different purpose entirely. As an IGP with system-shared memory and a 50 W TDP, it is designed for portable devices where power efficiency is critical. Its 57th percentile ranking and average score of 15270 place it near the NVIDIA GeForce GTX 580 and RTX 2060, making it adequate for lighter workloads but not competitive with modern discrete graphics cards.

Users choosing between these two should base their decision on the intended hardware platform. The 680M is the only option for systems relying on integrated graphics, since it cannot be installed as a separate card. The RX 7650 GRE, with its dual-slot design, 204 mm length, and 8-pin power connector, is a drop-in discrete solution for desktop PCs. The benchmark data provides no scenario where the 680M outperforms the RX 7650 GRE.
