AMD Radeon 8065S vs NVIDIA GeForce RTX 5080 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Radeon 8065S and the NVIDIA GeForce RTX 5080. The head-to-head benchmark array is empty, and neither part has a recorded average benchmark score in the comparison set. The AMD Radeon 8065S has an average benchmark score of 0 and no entries in its benchmark list, while the NVIDIA GeForce RTX 5080 has a substantial recorded benchmark profile.

The RTX 5080 delivers a 3DMark Steel Nomad DX12 score of 8637, a Geekbench OpenCL result of 235901, and a Geekbench Vulkan score of 255450. In Passmark tests, the RTX 5080 records 36565 in G3D, 21789 in GPU compute, 1415 in G2D, 389 in DirectX 9, 324 in DirectX 11, 208 in DirectX 10, and 151 in DirectX 12. Its average benchmark score is 56083, placing it at the 87th percentile of all GPUs in the database.

The AMD Radeon 8065S has no benchmark scores recorded, no nearest rivals listed, and sits at the 50th percentile with an average score of 0. This makes direct numeric comparison impossible. What can be compared are the architectural specifications and the RTX 5080's position against its own nearest rivals. The RTX 5080's average score of 56083 places it 0.6% ahead of the AMD Radeon 8060S, which scores 55757. It is 0.7% ahead of the AMD Radeon RX 6750 GRE 12 GB at 55698, and 2.3% ahead of the AMD Radeon Pro W5700X at 54828. The AMD Radeon RX 9070 GRE sits 2.2% ahead of the RTX 5080 with a score of 57367.

The RTX 5080 shows a narrow margin over its closest rival, the AMD Radeon 8060S, at only 0.6%. The spread across the entire nearest-rival group is small, roughly 4.5 percentage points from the lowest rival to the highest. This indicates that the RTX 5080 performs in a tightly contested tier where small percentage differences separate products. The 87th percentile placement confirms that the RTX 5080 ranks among the higher-performing GPUs in the database, but its nearest rivals demonstrate that the top of the stack is crowded.

The FP32 compute figures provide another angle. The RTX 5080 delivers 56.28 TFLOPS of FP32 performance, while the Radeon 8065S delivers 15.36 TFLOPS. That is a 3.66x difference in raw shader throughput. Texture rate shows a similar gap: 879.3 GTexel/s for the RTX 5080 versus 480.0 GTexel/s for the Radeon 8065S. Pixel rate goes in the same direction, 293.1 GPixel/s against 192.0 GPixel/s.

The Verdict

The data supports a clear split. The NVIDIA GeForce RTX 5080 is a discrete, dual-slot add-in card with a 360 W TDP, a 16-pin power connector, and a 750 W suggested PSU. It has 10752 shading units, 336 texture mapping units, 112 render output units, 84 RT cores, and 336 tensor cores. It carries 16 GB of GDDR7 memory on a 256-bit bus with 960.0 GB/s of bandwidth. It is a large physical card, 304 mm long, 137 mm tall, and 40 mm wide, which matches its high-power, high-throughput profile.

The AMD Radeon 8065S is an integrated graphics processor on a 55 W TDP with no power connectors and a portable-device-dependent display output. It uses system-shared memory with system-dependent bandwidth. It has 2560 shading units, 160 TMUs, 64 ROPs, and 40 RT cores. It has no tensor cores listed. Its die size is 308 mm², which is large for an integrated part, but its performance envelope is far below the RTX 5080.

Who should pick which, strictly from the data: the RTX 5080 is the choice for workloads that require high FP32 throughput, dedicated GDDR7 memory bandwidth, and tensor core acceleration. The Radeon 8065S is the choice for a compact, low-power integrated solution where the host system provides memory and the physical footprint is minimal. The RTX 5080's benchmark profile confirms it performs at a high level, while the Radeon 8065S has no recorded benchmark scores to validate any performance claim. The 8065S's 50th percentile placement with an average score of 0 indicates it sits at the median of the database distribution, but without measured scores, that placement carries little weight.

Its transistor count is 45,600 million, its die size is 378 mm², and its transistor density is 120.6 million per mm².

The Radeon 8065S has a base clock of 1295 MHz and a boost clock of 3000 MHz. The RTX 5080 has a base clock of 2295 MHz and a boost clock of 2617 MHz. The Radeon 8065S boosts much higher, but its shader count is far lower. The memory architectures are fundamentally different. The Radeon 8065S uses system-shared memory with system-dependent bandwidth, meaning performance scales with the host platform's memory configuration. The RTX 5080 has dedicated 16 GB of GDDR7 on a 256-bit bus delivering 960.0 GB/s.

The RTX 5080 includes 336 tensor cores; the Radeon 8065S lists none. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5080 has a 336-core tensor array, which the Radeon 8065S lacks entirely. The RTX 5080 also has more than twice the RT cores: 84 versus 40. The Radeon 8065S has no power connectors and a 55 W TDP, while the RTX 5080 requires a 16-pin connector, a 360 W TDP, and a 750 W suggested PSU.

Both use PCIe 5.0 x16 as the bus interface. The Radeon 8065S is an IGP with portable-device-dependent display outputs, while the RTX 5080 provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. The release dates differ: the RTX 5080 launched on 2025-01-29, while the Radeon 8065S is dated 2025-12-31. The RTX 5080 has a predecessor in the GeForce 40 series and a successor in the GeForce 60 series. The Radeon 8065S lists Polaris Mobile as its predecessor and no successor.

Where Each One Wins

The RTX 5080 wins on raw throughput metrics. Its FP32 rate of 56.28 TFLOPS is 3.66x the Radeon 8065S's 15.36 TFLOPS. Its texture rate of 879.3 GTexel/s beats 480.0 GTexel/s, and its pixel rate of 293.1 GPixel/s beats 192.0 GPixel/s. The RTX 5080 has 10752 shading units against 2560, 336 TMUs against 160, 112 ROPs against 64, and 84 RT cores against 40. The RTX 5080 also has 336 tensor cores, which the Radeon 8065S lacks. The RTX 5080's dedicated 16 GB GDDR7 memory with 960.0 GB/s bandwidth is a decisive advantage over system-shared memory with system-dependent bandwidth.

The Radeon 8065S wins on power efficiency and physical integration. Its 55 W TDP is far below the RTX 5080's 360 W. It requires no power connectors, while the RTX 5080 needs a 16-pin connector and a 750 W suggested PSU. The Radeon 8065S is an IGP with portable-device-dependent display outputs, meaning it fits into compact systems without a separate card. Its boost clock of 3000 MHz is higher than the RTX 5080's 2617 MHz, though the shader count difference overwhelms that clock advantage in compute workloads. The Radeon 8065S also uses a smaller die at 308 mm² versus 378 mm² and a smaller process node at 4 nm versus 5 nm.

The use-case split is clear. The RTX 5080 is for high-performance desktop systems that can accommodate a dual-slot, 304 mm long card with a 360 W power draw. It delivers measured benchmark results, a high average score, and the 87th percentile placement. The Radeon 8065S is for portable devices where power draw, physical space, and integrated memory sharing are the priorities. It trades away dedicated memory, tensor cores, and raw shader throughput for a 55 W envelope and no external power requirement.
