A: The Radeon 680M is built on RDNA 2.0 architecture using a 6 nm process, while the Radeon 8065S uses RDNA 3.5 architecture on a 4 nm process. The 8065S is part of the Navi Mobile (RX 8000M) generation, whereas the 680M belongs to the Navi II IGP (Rembrandt Mobile) generation.

Q: How do the shading unit counts compare between the two GPUs?

A: The Radeon 680M has 768 shading units, while the Radeon 8065S has 2560 shading units. This represents a 3.33x difference in shading hardware, which directly impacts the FP32 compute throughput.

Q: What is the FP32 performance difference?

A: The Radeon 680M delivers 3.379 TFLOPS of FP32 compute, while the Radeon 8065S delivers 15.36 TFLOPS. The 8065S is approximately 4.55x faster in raw single-precision floating-point performance.

Q: How do the boost clocks compare?

A: The Radeon 680M has a base clock of 2000 MHz and a boost clock of 2200 MHz. The Radeon 8065S has a lower base clock of 1295 MHz but a significantly higher boost clock of 3000 MHz.

Q: What are the power consumption figures for each GPU?

A: The Radeon 680M has a TDP of 50 W, while the Radeon 8065S has a TDP of 55 W. Despite the large performance gap, the 8065S consumes only 5 W more power.

Q: Do both GPUs support the same API feature set?

A: Yes, both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 680M has 12 ray tracing cores, while the 8065S has 40 ray tracing cores.

Architecture Differences

The two GPUs represent a substantial generational leap within AMD's integrated graphics lineup. The Radeon 680M is based on the Rembrandt+ chip, using RDNA 2.0 architecture on a 6 nm TSMC process. The Radeon 8065S uses the Gorgon Halo chip with RDNA 3.5 architecture on a 4 nm TSMC process. This process shrink allows the 8065S to pack significantly more hardware into its 308 mm² die, compared to the 680M's 208 mm² die. The 680M integrates 13,100 million transistors, while the 8065S transistor count is listed as unknown in the database.

The compute resources differ dramatically. The 680M features 768 shading units, 48 texture mapping units, and 32 raster operation pipelines. The 8065S scales this up to 2560 shading units, 160 TMUs, and 64 ROPs. Ray tracing hardware also expands from 12 RT cores on the 680M to 40 RT cores on the 8065S, reflecting the architectural improvements in RDNA 3.5. The shading unit increase is particularly notable: 2560 units represent more than triple the 680M's count, which drives the large compute throughput advantage.

The FP16 performance characteristics also differ. The 680M achieves 6.758 TFLOPS FP16 using a 2:1 ratio relative to FP32, meaning it processes half-precision at twice the rate. The 8065S achieves 15.36 TFLOPS FP16 at a 1:1 ratio, indicating that FP16 and FP32 throughput are identical on this architecture. This suggests different shader execution designs between RDNA 2.0 and RDNA 3.5.

Clock behavior diverges as well. The 680M runs at a base of 2000 MHz and boosts to 2200 MHz, while the 8065S starts at a lower 1295 MHz base but boosts to 3000 MHz. The higher boost ceiling on the 8065S, combined with its larger shader array, produces the performance separation. The 8065S also uses a PCIe 5.0 x16 bus interface, compared to the 680M's PCIe 4.0 x8, though both rely on system shared memory with bandwidth dependent on the host platform.

Both GPUs are integrated parts with no power connectors, IGP slot width, and portable device dependent display outputs. The 8065S has a production status of Active with a release date of 2025-12-31, while the 680M is also Active with a release date of 2023-01-02. The 680M's predecessor is the Vega II IGP and its successor is the Navi III IGP, while the 8065S lists the Polaris Mobile as its predecessor and has no successor recorded.

Head-to-Head Benchmarks

The database currently contains no direct head-to-head benchmark comparisons between the AMD Radeon 680M and the AMD Radeon 8065S. The head-to-head results array is empty, and neither GPU has recorded wins in this matchup. However, individual benchmark data for the 680M provides context for its performance tier.

The Radeon 680M achieves a score of 378 in the 3DMark Steel Nomad DX12 test, 23468 in Geekbench OpenCL, and 21965 in Geekbench Vulkan. Its average benchmark score across all recorded tests is 15270, placing it at the 57th percentile among all GPUs in the database. The 8065S has no recorded benchmark scores yet, with an average benchmark score of 0 and a 50th percentile ranking.

The 680M's nearest rivals in the database include the NVIDIA GeForce GTX 580 with an average score of 15283 and a delta of -0.1%, the NVIDIA GeForce RTX 2060 with 15290 and -0.1%, the NVIDIA GeForce RTX 3050 OEM with 15199 and 0.5%, and the AMD Radeon RX 7600 with 15171 and 0.7%. These narrow deltas indicate the 680M sits in a tightly packed performance cluster, within about 1% of several discrete desktop GPUs from both NVIDIA and AMD.

The architectural specifications suggest the 8065S should substantially outperform the 680M based on compute resources alone. The 8065S delivers 15.36 TFLOPS FP32 versus 3.379 TFLOPS for the 680M, a 4.55x difference. Texture rate scales similarly: 480.0 GTexel/s versus 105.6 GTexel/s. Pixel rate shows a 2.73x gap at 192.0 GPixel/s versus 70.40 GPixel/s. However, without direct benchmark measurements for the 8065S, the actual performance delta remains unquantified in the database. The 680M's existing scores serve as a baseline reference, while the 8065S awaits its first recorded benchmarks.

The Verdict

The recorded data shows a clear generational divide between these two integrated GPUs. The Radeon 680M has established benchmark results with an average score of 15270 and sits at the 57th percentile, trading blows within 1% of several discrete desktop GPUs. The Radeon 8065S, by contrast, has no recorded benchmarks yet and holds a 50th percentile placeholder ranking.

The architectural specifications heavily favor the 8065S. Its 2560 shading units, 160 TMUs, 64 ROPs, and 40 RT cores represent a massive resource increase over the 680M's 768 shading units, 48 TMUs, 32 ROPs, and 12 RT cores. The 4.55x FP32 advantage and 4.55x texture rate advantage support the expectation of a substantial performance lead, though direct measurements are pending.

The 8065S achieves this with only a 5 W higher TDP, at 55 W versus 50 W. This efficiency comes from the 4 nm process node, which enables higher boost clocks reaching 3000 MHz despite a lower 1295 MHz base clock. The 680M's older 6 nm process limits its clocks to 2200 MHz boost.

The 8065S targets a later generation with its Navi Mobile (RX 8000M) designation and PCIe 5.0 x16 interface, while the 680M belongs to the Navi II IGP generation with PCIe 4.0 x8. The 8065S also carries a larger 308 mm² die, suggesting a more complex implementation overall.

For users seeking an integrated GPU with proven performance data, the 680M offers a known quantity: its benchmark scores place it alongside the RTX 2060 and GTX 580 in average performance. For those looking at the newer platform, the 8065S presents a compelling specification sheet with more than four times the compute throughput and triple the ray tracing cores, but its real-world performance remains unmeasured in the database. The data indicates the 8065S should be the stronger part when benchmarks arrive, but the 680M currently holds the only recorded performance evidence.
