AMD Radeon 8065S vs AMD Radeon RX 6550S Comparison

The Verdict

The database places both the AMD Radeon 8065S and the AMD Radeon RX 6550S at the 50th percentile among all GPUs, with identical average benchmark scores of zero, meaning the recorded data does not separate them on raw aggregate performance. The 8065S, built on RDNA 3.5 with a 4 nm process, delivers 15.36 TFLOPS of FP32 compute, while the RX 6550S, based on RDNA 2.0 on a 6 nm node, offers 4.915 TFLOPS. That is a 3.13x gap in raw floating-point throughput, which indicates the 8065S has substantially more raw shader capacity.

However, the RX 6550S has dedicated 4 GB of GDDR6 memory on a 64-bit bus with 128.0 GB/s of bandwidth, whereas the 8065S relies entirely on system shared memory, with bandwidth listed as system dependent. For workloads that are sensitive to dedicated memory latency and consistent bandwidth, the RX 6550S may hold an advantage, despite its lower compute. The 8065S also draws 55 W versus 50 W for the RX 6550S, a modest difference given the compute disparity.

The data supports a clear split: the 8065S is the pick for compute-heavy tasks and modern API workloads, the RX 6550S is the pick for scenarios where a fixed, local memory pool matters more than raw shader count. Neither part has a benchmark win recorded in the head-to-head table, so the verdict rests on architectural and memory characteristics rather than measured frame rates.

Where Each One Wins

The 8065S wins in raw compute throughput. Its FP32 figure of 15.36 TFLOPS is exactly triple the RX 6550S's 4.915 TFLOPS. The texture rate also favors the 8065S: 480.0 GTexel/s versus 153.6 GTexel/s, a 3.13x margin. Pixel rate follows the same pattern, with the 8065S at 192.0 GPixel/s against 76.80 GPixel/s. Any workload that scales with shader count, texture fetching, or fill rate will favor the 8065S decisively.

The RX 6550S wins in memory determinism. It has 4 GB of GDDR6, a 64-bit bus, and a fixed 128.0 GB/s bandwidth. The 8065S has no dedicated memory, no fixed bus width, and no specified bandwidth, only "System Shared" and "System Dependent". For applications that cannot tolerate variable memory performance, the RX 6550S provides a consistent, known quantity. Its base clock is also higher at 2000 MHz versus 1295 MHz, although the 8065S boosts to 3000 MHz against 2400 MHz.

In API support, both parts list DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so there is no split there. The RX 6550S has ray tracing cores, 16 of them, while the 8065S has 40, so the 8065S has more RT hardware. The RX 6550S also has a higher game clock specification of 2170 MHz, which is not present for the 8065S.

The 8065S uses a PCIe 5.0 x16 interface, the RX 6550S uses PCIe 4.0 x4, giving the 8065S a wider and newer bus for system shared memory access. The 8065S also has a larger die at 308 mm² versus 107 mm², and it is built on a smaller 4 nm node versus 6 nm.

Head-to-Head Benchmarks

The head-to-head benchmark table contains no entries, so there are no recorded wins for either GPU in the database. This means the comparison must rely on the fixed specifications. The largest win for the 8065S is in FP32 compute: 15.36 TFLOPS against 4.915 TFLOPS, a 10.445 TFLOPS difference. The texture rate shows the same proportional gap, 480.0 GTexel/s versus 153.6 GTexel/s, and the pixel rate is 192.0 GPixel/s versus 76.80 GPixel/s. These numbers indicate the 8065S has 3.13x the shading, texturing, and pixel filling capacity of the RX 6550S.

The RX 6550S does not have a single specification that beats the 8065S by a similar margin. Its base clock is higher, 2000 MHz versus 1295 MHz, but the boost clock is lower, 2400 MHz versus 3000 MHz. Its memory bandwidth is fixed at 128.0 GB/s, while the 8065S's bandwidth is system dependent, so no direct comparison is possible. The RX 6550S has a smaller die, 107 mm² versus 308 mm², and a lower TDP, 50 W versus 55 W, but those are not performance wins.

The 8065S also wins on interface width: PCIe 5.0 x16 versus PCIe 4.0 x4. This is relevant because the 8065S relies on system shared memory, so a wider, newer bus can reduce the penalty of shared memory access. The RX 6550S does not need that bandwidth because it has local GDDR6.

The recorded data gives no wins to either side in the head-to-head table. The specification sheet, however, favors the 8065S on every compute metric and on ray tracing core count. The RX 6550S offers a more predictable memory subsystem and a higher base clock, but no measured benchmark advantage is present in the database.
