AMD Radeon 8065S vs AMD Radeon RX 7700 XT Comparison

The Verdict

The database comparison places the AMD Radeon RX 7700 XT in a clearly superior position. The RX 7700 XT holds an average benchmark score of 22549, placing it in the 67th percentile of all GPUs, while the Radeon 8065S shows no recorded average score and sits at the 50th percentile. With 3456 shading units against the 8065S's 2560, and a 35.17 TFLOPS FP32 throughput versus 15.36 TFLOPS, the RX 7700 XT delivers more than double the raw compute performance.

The RX 7700 XT is the appropriate choice for desktop users needing dedicated graphics with 12 GB of GDDR6 memory and 432.0 GB/s of bandwidth. Its 245 W TDP and dual-slot design with 2x 8-pin power connectors indicate a conventional desktop part. The 8065S, by contrast, is an integrated graphics processor with a 55 W TDP, no power connectors, and system-shared memory, making it suitable for portable devices where power efficiency and space are constrained. The data clearly separates the two: one is a high-performance discrete card, the other is an IGP for mobile platforms.

Architecture Differences

The two GPUs belong to different generations and architectures within AMD's lineup. The Radeon 8065S uses the RDNA 3.5 architecture on a 4 nm TSMC process, built on the "Gorgon Halo" chip, and belongs to the Navi Mobile (RX 8000M) generation. The RX 7700 XT uses the older RDNA 3.0 architecture on a 5 nm TSMC process, with the "Navi 32" chip, part of the Navi III (RX 7000) generation. The 8065S is manufactured on a smaller node, suggesting a focus on power efficiency for mobile use.

The transistor counts differ dramatically. The RX 7700 XT lists 28,100 million transistors on a 346 mm² die with a density of 81.2M per mm². The 8065S has an unknown transistor count but a smaller die size of 308 mm². The RX 7700 XT also has a higher transistor density and larger die, which correlates with its higher compute throughput.

Memory architecture separates the two fundamentally. The 8065S uses system-shared memory, with bandwidth described as system dependent, meaning its performance scales with the host system's RAM configuration. The RX 7700 XT features 12 GB of dedicated GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The RX 7700 XT's memory clock runs at 2250 MHz with 18 Gbps effective speed, while the 8065S's memory clock is simply listed as "System Shared."

Feature sets show some overlap. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7700 XT has 54 ray tracing cores versus the 8065S's 40, and 96 ROPs versus 64. The RX 7700 XT also has more texture mapping units at 216 versus 160. The 8065S does have a higher boost clock at 3000 MHz compared to the RX 7700 XT's 2544 MHz, but the latter has a higher base clock at 1435 MHz versus 1295 MHz.

Specification Differences

The two GPUs differ across nearly every hardware specification. The process node is 4 nm for the 8065S and 5 nm for the RX 7700 XT, both from TSMC. Die size is 308 mm² for the 8065S and 346 mm² for the RX 7700 XT, with transistor count unknown for the former and 28,100 million for the latter. The transistor density is listed as null for the 8065S and 81.2M per mm² for the RX 7700 XT.

Clock speeds show a mixed picture. The 8065S has a base clock of 1295 MHz and boost of 3000 MHz, while the RX 7700 XT has a base of 1435 MHz, boost of 2544 MHz, and a game clock of 2171 MHz. Memory clocks are "System Shared" for the 8065S versus 2250 MHz with 18 Gbps effective for the RX 7700 XT.

Compute units differ significantly. The 8065S has 2560 shading units, 160 TMUs, 64 ROPs, and 40 RT cores. The RX 7700 XT has 3456 shading units, 216 TMUs, 96 ROPs, and 54 RT cores.

Release dates and predecessors set them apart in time. The 8065S was released at the end of 2025 with a predecessor of Polaris Mobile. The RX 7700 XT was released in September 2023 with a predecessor of Navi II and a successor of Navi IV. The RX 7700 XT has a launch MSRP of 449 USD.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between the two GPUs, and the 8065S has an empty benchmark list. However, the RX 7700 XT's individual benchmark scores and its standing against nearby rivals provide context for performance expectations.

The RX 7700 XT's strongest recorded results include a 3DMark Steel Nomad DX12 score of 3316, a Geekbench OpenCL score of 138383, and a Geekbench Vulkan score of 46443. In Passmark tests, it scores 22547 in G3D and 12912 in GPU compute, with lower scores in older APIs such as 294 in DirectX 9, 232 in DirectX 11, and 119 in DirectX 10.

Relative to its nearest rivals, the RX 7700 XT shows tight competition. It sits 0.5% above the NVIDIA GeForce RTX 5060 Mobile in average score, 0.8% below the RTX 4060 Mobile, 1.5% below the RTX 2080, and 1.7% above the AMD Radeon RX 5700. These small deltas indicate the RX 7700 XT performs in a close cluster with these cards, with no dominant margin over any of them.

The 8065S's position is less clear due to missing benchmark data. Its 50th percentile ranking and lack of an average score mean the database cannot quantify its performance relative to the RX 7700 XT or any other GPU. The specifications suggest a large gap: the RX 7700 XT's 35.17 TFLOPS FP32 is 129% higher than the 8065S's 15.36 TFLOPS, and its 432.0 GB/s memory bandwidth vastly exceeds the system-dependent bandwidth of the 8065S.

The RX 7700 XT also leads in pixel rate by 27% and texture rate by 14%, with 50% more shading units and 35% more RT cores. These are the decisive margins in this comparison. The 8065S's only specification advantages are its smaller process node, higher boost clock, and PCIe 5.0 interface, none of which compensate for its compute deficit in the recorded data.
