AMD Radeon 8065S vs AMD Radeon RX 7600S Comparison

The Verdict

The AMD Radeon 8065S and the AMD Radeon RX 7600S are both integrated laptop-class GPUs from AMD, but they target different performance tiers. The RX 7600S is a mature RDNA 3.0 part with recorded benchmark data, while the 8065S is a newer RDNA 3.5 design that currently has no individual benchmark scores in the database. The RX 7600S holds a 60th percentile ranking among all GPUs, with an average benchmark score of 16696. The 8065S, despite its newer architecture and larger die, sits at the 50th percentile with an average score of zero, indicating that its actual performance has not yet been measured in the database. Therefore, the RX 7600S is the only option with verifiable performance data, making it the safe choice for anyone who needs confirmed results today. The 8065S represents a future option that may deliver higher performance based on its specifications, but its lack of measured benchmarks means no claims can be made about its real-world capability. The data shows that the RX 7600S is the only card with a proven track record, while the 8065S is an unproven entity in the current database.

Where Each One Wins

The AMD Radeon RX 7600S has concrete wins across multiple benchmark suites. In 3DMark Steel Nomad DX12, it scores 1888. In Geekbench OpenCL, it reaches 68012, and in Geekbench Vulkan, it posts 73868. Passmark results show 15408 in G3D, 6520 in GPU Compute, and 211 in DirectX 9. The RX 7600S also records 140 in DirectX 11, 74 in DirectX 10, 65 in DirectX 12, and 776 in G2D. These numbers establish a clear performance baseline across both compute and graphics workloads.

The AMD Radeon 8065S has no benchmark scores recorded in the database, so it cannot claim any wins in measured tests. However, its specifications suggest potential advantages in certain areas. The 8065S uses a 4 nm process node compared to the RX 7600S's 6 nm node, which typically allows for higher efficiency. The 8065S also has a larger die size at 308 mm² versus 204 mm² for the RX 7600S. The 8065S features 2560 shading units, 160 TMUs, and 40 ray tracing cores, while the RX 7600S has 1792 shading units, 112 TMUs, and 28 ray tracing cores. These counts indicate the 8065S is configured for higher throughput in shader-heavy and ray tracing workloads, provided its drivers and thermal constraints allow full utilization. The 8065S also lists a boost clock of 3000 MHz versus 2200 MHz for the RX 7600S, which could translate into higher peak performance in burst scenarios.

Architecture Differences

The two GPUs belong to different architectural generations. The AMD Radeon 8065S uses RDNA 3.5 architecture with the Gorgon Halo chip, part of the Navi Mobile (RX 8000M) generation. The AMD Radeon RX 7600S uses RDNA 3.0 architecture with the Navi 33 chip, codenamed Hotpink Bonefish, part of the RX 7000 series. The process nodes differ significantly: the 8065S is built on TSMC's 4 nm process, while the RX 7600S uses TSMC's 6 nm process. The transistor counts are starkly different: the RX 7600S contains 13,300 million transistors, while the 8065S has an unknown transistor count. Die sizes also diverge, with the 8065S at 308 mm² and the RX 7600S at 204 mm², giving the RX 7600S a transistor density of 65.2 million per mm².

Memory configurations are another major divergence. The RX 7600S has 8 GB of dedicated GDDR6 memory on a 128-bit bus with 256.0 GB/s bandwidth and a memory clock of 2000 MHz (16 Gbps effective). The 8065S uses system-shared memory, meaning it relies on the host system's RAM for both capacity and bandwidth, with the bus width also being system-shared. This makes the 8065S's memory performance entirely dependent on the laptop's memory configuration, which is a critical difference for bandwidth-sensitive workloads.

Clock speeds differ substantially. The RX 7600S has a base clock of 1500 MHz, a boost clock of 2200 MHz, and a game clock of 1865 MHz. The 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz, with no game clock specified. The 8065S's higher boost clock suggests it can reach higher peak frequencies, but its lower base clock indicates a wider clock range.

Compute capabilities show a mixed picture. The 8065S delivers 15.36 TFLOPS FP32 and 15.36 TFLOPS FP16 (1:1 ratio). The RX 7600S delivers 15.77 TFLOPS FP32 and 31.54 TFLOPS FP16 (2:1 ratio). This means the RX 7600S has a higher FP32 peak and significantly higher FP16 throughput due to its 2:1 rate. Pixel and texture rates also differ: the 8065S achieves 192.0 GPixel/s and 480.0 GTexel/s, while the RX 7600S achieves 140.8 GPixel/s and 246.4 GTexel/s. The 8065S wins decisively in texture fill rate, which benefits texel-heavy rendering.

Power and connectivity differ as well. The 8065S has a TDP of 55 W, while the RX 7600S has a TDP of 75 W. Both are IGP slot width with no power connectors. The bus interface is PCIe 5.0 x16 for the 8065S versus PCIe 4.0 x16 for the RX 7600S. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The 8065S's release date is listed as 2025-12-31, while the RX 7600S was released on 2023-01-03, making the RX 7600S the older, established product.

Head-to-Head Benchmarks

Direct benchmark comparisons between these two GPUs are impossible because the 8065S has no recorded scores in the database. The RX 7600S, however, has a full suite of results that establish its performance profile. In 3DMark Steel Nomad DX12, the RX 7600S scores 1888. Its Geekbench OpenCL score is 68012, and its Geekbench Vulkan score is 73868. Passmark results include 15408 in G3D, 6520 in GPU Compute, 776 in G2D, 211 in DirectX 9, 140 in DirectX 11, 74 in DirectX 10, and 65 in DirectX 12. These scores place the RX 7600S at the 60th percentile among all GPUs.

The RX 7600S's nearest rivals in the database provide context for its performance. The NVIDIA T400 4 GB has an average score of 16792, which is 0.6% lower than the RX 7600S. The NVIDIA T400 scores 16508, which is 1.1% higher than the RX 7600S. The NVIDIA GeForce RTX 5090 D V2 scores 16504, also 1.1% higher. The NVIDIA Tesla M4 scores 16932, which is 1.4% lower. These deltas show that the RX 7600S sits in a tight competitive band, with all rivals within 1.4% of its average score.

For the 8065S, the specification-based differences suggest where it could outperform the RX 7600S once measured. The 8065S has a 36% higher texture rate (480.0 GTexel/s versus 246.4 GTexel/s), a 36% higher pixel rate (192.0 GPixel/s versus 140.8 GPixel/s), and 43% more shading units (2560 versus 1792). It also has 43% more ray tracing cores (40 versus 28). These advantages could translate into wins in texture-heavy scenes and ray tracing workloads. However, the RX 7600S has a 2.7% higher FP32 throughput (15.77 TFLOPS versus 15.36 TFLOPS) and more than double the FP16 throughput (31.54 TFLOPS versus 15.36 TFLOPS), which could keep it ahead in compute-heavy tasks.

The power envelope favors the 8065S at 55 W versus 75 W for the RX 7600S, meaning the newer part may achieve its performance with lower power draw. The 8065S also uses a newer PCIe 5.0 x16 interface versus PCIe 4.0 x16, which could reduce data transfer bottlenecks with system memory. The RX 7600S's dedicated 8 GB GDDR6 with 256.0 GB/s bandwidth provides a fixed memory advantage, whereas the 8065S's system-shared memory bandwidth is variable and dependent on the laptop's RAM configuration.

The database currently shows the RX 7600S as the only GPU with verified benchmark data. Its average score of 16696 and 60th percentile ranking give it a concrete position in the market. The 8065S's 50th percentile and zero average score reflect its unmeasured status, not its potential. Until benchmarks are recorded for the 8065S, any comparison between the two relies entirely on architectural specifications. The recorded data shows the RX 7600S as a solid, mid-pack performer, while the 8065S remains a promising but unverified entry in the Navi Mobile lineup.
