AMD Radeon 8065S vs NVIDIA GeForce RTX 4080 SUPER Comparison

AMD Radeon 8065S and NVIDIA GeForce RTX 4080 SUPER occupy opposite ends of the mobile and desktop graphics spectrum. The 8065S is an integrated graphics processor built into a 55 W package, while the RTX 4080 SUPER is a triple-slot, 320 W discrete card. The recorded data shows a fundamental split: the RTX 4080 SUPER dominates every measurable benchmark, while the 8065S offers a unique form factor and power profile. The RTX 4080 SUPER holds the 86th percentile among all GPUs, whereas the 8065S sits at the 50th percentile. This page breaks down where each part wins, the architectural divergence, and the specification gaps that define their respective roles.

Where Each One Wins

The RTX 4080 SUPER wins every recorded performance test. Its average benchmark score is 54,209, while the 8065S has no recorded benchmark scores and an average score of zero. In the database, the RTX 4080 SUPER posts a 3DMark Steel Nomad DX12 score of 6,600, a Geekbench OpenCL score of 219,065, and a Geekbench Vulkan score of 260,075. Passmark results reinforce the pattern: G3D at 34,245, GPU Compute at 19,822, DirectX 11 at 301, DirectX 10 at 193, and DirectX 12 at 134. The 8065S offers no comparable figures, meaning its only "win" is the absence of a discrete power draw and physical footprint.

The use-case split is therefore not about performance but about deployment. The 8065S uses system-shared memory, which means its bandwidth and capacity depend entirely on the host platform. The RTX 4080 SUPER carries 16 GB of dedicated GDDR6X on a 256-bit bus with 736.3 GB/s of bandwidth. The data indicates the 8065S is designed for portable devices where a 55 W integrated part is the only viable option. The RTX 4080 SUPER targets high-end desktop builds with a suggested 700 W power supply and a 310 mm length. Benchmark results indicate the RTX 4080 SUPER wins all compute and rasterization workloads, while the 8065S wins on integration and power efficiency.

Architecture Differences

The two GPUs share no common architectural lineage. The 8065S uses AMD's RDNA 3.5 architecture on a 4 nm TSMC process, built around the Gorgon Halo chip. The RTX 4080 SUPER uses NVIDIA's Ada Lovelace architecture on a 5 nm TSMC process with the AD103 chip. Process node favors the 8065S at 4 nm versus 5 nm, but the RTX 4080 SUPER compensates with a much larger die: 379 mm² versus 308 mm². Transistor counts diverge sharply. The RTX 4080 SUPER packs 45,900 million transistors with a density of 121.1M per mm². The 8065S has an unknown transistor count, so the density comparison cannot be completed.

Core configuration differences are massive. The RTX 4080 SUPER has 10,240 shading units, 320 texture mapping units, 112 render output units, 80 ray tracing cores, and 320 tensor cores. The 8065S has 2,560 shading units, 160 TMUs, 64 ROPs, and 40 ray tracing cores, with no tensor cores listed. The RTX 4080 SUPER therefore has 4 times the shading units, 2 times the TMUs, and 2 times the ray tracing cores. The 8065S lacks tensor cores entirely, which affects any workload relying on dedicated AI acceleration. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature support is identical.

Memory architecture is the most consequential difference. The 8065S uses system-shared memory with a system-dependent bandwidth, while the RTX 4080 SUPER uses 16 GB of GDDR6X with a dedicated 256-bit bus. The RTX 4080 SUPER's memory clock is 1438 MHz, translating to 23 Gbps effective and 736.3 GB/s of bandwidth. The 8065S has no fixed memory specifications, which makes its performance platform-dependent. Clock behavior also differs: the 8065S boosts to 3000 MHz from a 1295 MHz base, while the RTX 4080 SUPER boosts to 2550 MHz from a 2295 MHz base. The 8065S's higher boost clock does not overcome its far smaller core count.

Head-to-Head Benchmarks

Direct benchmark comparisons are impossible because the 8065S has no recorded scores. The head-to-head benchmark array is empty, and winsA and winsB are both zero. The RTX 4080 SUPER's nearest rival results provide context instead. It trails the NVIDIA GeForce RTX 4080 by 0.1% in average score, sits 1.1% behind the AMD Radeon Pro W5700X, 2.7% behind the AMD Radeon RX 6750 GRE 12 GB, and 2.8% behind the AMD Radeon 8060S. These deltas are small, indicating the RTX 4080 SUPER is tightly clustered with high-end parts in the database. The 8065S has no nearest rivals listed, so no percentile or delta comparisons exist for it.

The RTX 4080 SUPER's individual benchmark scores show its strongest areas. The Geekbench Vulkan score of 260,075 exceeds the OpenCL score of 219,065, suggesting Vulkan is the more favorable API for this GPU. Passmark results show a G3D score of 34,245 against a GPU Compute score of 19,822, meaning rasterization performance is nearly twice the compute figure. The 3DMark Steel Nomad DX12 score of 6,600 is the only modern gaming workload recorded. The 8065S has no equivalent data, so its performance can only be inferred from its specifications: 15.36 TFLOPS FP32, 192.0 GPixel/s pixel rate, and 480.0 GTexel/s texture rate. The RTX 4080 SUPER achieves 52.22 TFLOPS FP32, 285.6 GPixel/s, and 816.0 GTexel/s.

The FP32 gap is 3.4 times in favor of the RTX 4080 SUPER. The pixel rate gap is 1.49 times, and the texture rate gap is 1.7 times. These ratios confirm the RTX 4080 SUPER's dominance in raw throughput. The 8065S's 3000 MHz boost clock is 17.6% higher than the RTX 4080 SUPER's 2550 MHz boost, but the core count difference overwhelms the clock advantage. The 8065S's FP16 rate matches its FP32 rate at a 1:1 ratio, as does the RTX 4080 SUPER, so neither part gains a half-precision advantage.

Production status: active versus end-of-life. Release date: 2025-12-31 versus 2024-01-30. The RTX 4080 SUPER has a launch MSRP of 999 USD.

The RTX 4080 SUPER uses a newer PCIe 5.0 interface on the 8065S, but the RTX 4080 SUPER's PCIe 4.0 x16 is sufficient for its bandwidth needs. The 8065S's integrated nature means no power connectors and an IGP slot width. The RTX 4080 SUPER requires a triple-slot cooler and a 700 W power supply. The 8065S's display outputs depend on the portable device, while the RTX 4080 SUPER offers a fixed set of HDMI and DisplayPort outputs.

The Verdict

The data points to a clear choice for desktop users: the RTX 4080 SUPER. It wins every benchmark category, holds the 86th percentile, and delivers 52.22 TFLOPS FP32 performance. Its nearest rivals, the RTX 4080, Radeon Pro W5700X, Radeon RX 6750 GRE 12 GB, and Radeon 8060S, all sit within 2.8% of its average score, confirming its position in the high-end tier. The 8065S cannot compete on raw numbers, and its lack of recorded benchmarks means no performance verification exists in the database.

The 8065S suits a completely different environment. Its 55 W TDP, IGP slot width, and lack of power connectors make it a candidate for portable devices. The system-shared memory design means its performance scales with the host system's memory, which is a tradeoff versus the RTX 4080 SUPER's fixed 736.3 GB/s. The 8065S's 3000 MHz boost clock and PCIe 5.0 x16 interface are its standout features, but they do not offset the 4x shading unit deficit and the absence of tensor cores.

Production status separates them further. The 8065S is active, while the RTX 4080 SUPER is end-of-life with a successor in the GeForce 50 series. Buyers seeking current availability would look at the 8065S, while those seeking maximum performance would look at the RTX 4080 SUPER's recorded results. The 8065S's release date of 2025-12-31 is nearly two years after the RTX 4080 SUPER's 2024-01-30 release. The verdict from the database is straightforward: the RTX 4080 SUPER is the performance leader by every metric, and the 8065S is an integrated part with a different purpose, defined by its power envelope and platform dependency rather than benchmark victories.
