AMD Radeon 8060S vs AMD Radeon RX 6650M XT Comparison

Head-to-Head Benchmarks

The only directly comparable benchmark in the database is the Geekbench OpenCL test, and the results show a clear edge for the newer architecture. The AMD Radeon 8060S scores 84,626 points in Geekbench OpenCL, while the AMD Radeon RX 6650M XT scores 76,904 points. This represents a 9.1% lead for the Radeon 8060S, a meaningful gap in raw compute throughput.

When placed against the broader field, the RX 665M XT sits at the 91st percentile of all GPUs, with an average benchmark score of 76,904. Its nearest rivals include the NVIDIA GeForce RTX 5090 D at 77,712 points (1% higher), the AMD Radeon RX 6850M XT at 78,940 points (2.6% higher), and the NVIDIA Tesla P100 PCIe 12 GB at 79,396 points (3.1% higher). The Radeon 8060S, by contrast, holds the 87th percentile, with an average score of 55,757 across its recorded benchmarks, which include a 3DMark Steel Nomad DX12 result of 2,162 and a Geekbench Vulkan score of 80,483.

The delta between the two in OpenCL is significant, but it is notably the 8060S's average benchmark score is dragged down by the inclusion of its 3DMark result, which uses a different scoring scale. In the OpenCL test specifically, the 8060S is 9.1% ahead of the RX 665M XT. The Radeon 8060S also shows a 4.6% advantage over its own nearest rival, the NVIDIA GeForce RTX 5080, which scores 56,083 points (0.6% higher than the 8060S's average). Meanwhile, the RX 665M XT trails its nearest rivals by a narrower margin, with the closest competitor, the RTX 5090 D, only 1% faster.

Where Each One Wins

The Radeon 8060S wins the only head-to-head benchmark recorded, the Geekbench OpenCL test, with a 9.1% margin. That makes it the stronger choice for compute-heavy workloads that rely on OpenCL acceleration, such as certain rendering tasks, physics simulations, or machine learning inference. Its higher shading unit count (2,560 versus 2,048) and higher boost clock (2,900 MHz versus 2,416 MHz) contribute directly to this advantage, yielding 14.85 TFLOPS of FP32 performance compared to 9.896 TFLOPS for the RX 665M XT.

The RX 665M XT, however, has no benchmark wins recorded against the 8060S. Its strengths lie elsewhere in the database. It has a higher base clock (2,068 MHz versus 1,295 MHz), which could translate to better sustained performance in scenarios where boost clocks cannot be maintained due to thermal or power constraints. It also has a much lower power draw in terms of its fixed specifications, though the 8060S is rated at just 55 W TDP compared to 120 W for the RX 665M XT. Notably, the RX 665M XT has dedicated GDDR6 memory with 8 GB capacity and 256.0 GB/s bandwidth, while the 8060S relies on system-shared memory with bandwidth described only as "System Dependent." For gaming workloads that are sensitive to memory bandwidth, the RX 665M XT's dedicated VRAM could offer more predictable performance, even if its raw compute throughput is lower.

The 8060S also has a higher pixel rate (185.6 GPixel/s versus 154.6 GPixel/s) and texture rate (464.0 GTexel/s versus 309.2 GTexel/s), which suggests it can handle fill-rate-bound scenarios, such as high-resolution rendering with heavy post-processing, more efficiently. The RX 665M XT's advantage in the database is more about efficiency per watt at its fixed TDP, although the 8060S draws less power overall, making it the more power-frugal option despite delivering higher performance.

Architecture Differences

The two GPUs come from different generations of AMD's RDNA architecture. The RX 665M XT is built on RDNA 2.0, using the Navi 23 chip, while the Radeon 8060S uses RDNA 3.5 with the Strix Halo chip. The process node tells a similar story: the RX 665M XT is fabricated on TSMC's 7 nm process, while the 8060S uses the newer 4 nm node. This node shrink is one reason the 8060S can achieve higher clock speeds and better efficiency despite having more shading units.

The RX 665M XT packs 11,060 million transistors on a 237 mm² die, giving a transistor density of 46.7 million per square millimeter. The 8060S has a larger die at 308 mm², but its transistor count is listed as unknown, so a direct density comparison is not possible. The 8060S does have a higher number of shading units (2,560 versus 2,048), TMUs (160 versus 128), and ray tracing cores (40 versus 32). Both have 64 ROPs.

Memory architecture differs substantially. The RX 665M XT uses 8 GB of GDDR6 on a 128-bit bus, delivering 256.0 GB/s of bandwidth. The 8060S has no dedicated VRAM; its memory size, type, and bus width are all listed as "System Shared," with bandwidth dependent on the host system. This means the 8060S's memory performance is not fixed in the database but varies with the platform it is installed in.

Clock behavior also diverges. The RX 665M XT has a base clock of 2,068 MHz, a game clock of 2,162 MHz, and a boost clock of 2,416 MHz. The 8060S starts at a much lower base of 1,295 MHz but boosts to 2,900 MHz, a 2.24x ratio between base and boost. This suggests the 8060S relies more heavily on boost behavior to achieve its performance, while the RX 665M XT has a steadier clock profile. The FP16 throughput also differs: the RX 665M XT achieves 19.79 TFLOPS via a 2:1 ratio, while the 8060S delivers 14.85 TFLOPS at a 1:1 ratio, meaning it does not double FP16 throughput the way the older architecture does.

Both GPUs share the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are IGP slot-width devices with no power connectors, and both use portable-device-dependent display outputs. The bus interface differs, with the RX 665M XT using PCIe 4.0 x8 and the 8060S using PCIe 5.0 x16, which gives the newer part more bandwidth to the host system, though the practical impact depends on the workload.

The Verdict

The data points to a clear choice for users who prioritize raw compute performance: the AMD Radeon 8060S. It wins the only head-to-head benchmark recorded, delivering 9.1% higher OpenCL performance than the RX 665M XT. It also offers substantially higher FP32 throughput (14.85 TFLOPS versus 9.896 TFLOPS), more shading units, higher boost clocks, and a newer 4 nm process node. For applications that scale with shading unit count and clock speed, such as 3D rendering or compute offload, the 8060S is the stronger option.

However, the RX 665M XT has its own case. Its dedicated 8 GB GDDR6 memory with 256.0 GB/s bandwidth provides fixed, predictable memory performance, unlike the 8060S's system-shared memory, which is dependent on the host platform. For gaming workloads that are bandwidth-sensitive, the RX 665M XT could offer more consistent frame pacing. Its higher base clock of 2,068 MHz versus 1,295 MHz also suggests it maintains performance more steadily under sustained load, whereas the 8060S depends on boosting to 2,900 MHz to reach its potential.

The 8060S is also the more power-efficient part on paper, with a 55 W TDP versus 120 W for the RX 665M XT, a notable advantage in thin-and-light portable devices. The RX 665M XT is end-of-life, while the 8060S is active production, which may matter for long-term availability.

The database records one win for the 8060S and zero for the RX 665M XT. If the choice is between these two for a new build, the performance data favors the 8060S in compute workloads. If the system relies on fixed memory bandwidth and cannot accommodate higher power draw, the RX 665M XT remains a viable alternative, but it does not outscore the 8060S in any recorded test. The verdict, strictly from the recorded data, is that the AMD Radeon 8060S is the faster GPU, with the RX 665M XT holding value only in scenarios where its dedicated VRAM and steadier clock profile matter more than raw throughput.
