AMD Radeon 8065S vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The Verdict

The database comparison between the AMD Radeon 8065S and the NVIDIA GeForce RTX 5070 Ti Mobile shows two very different mobile graphics solutions. The RTX 5070 Ti Mobile is the clear performance leader in every recorded benchmark, with an average benchmark score of 35,435 and a percentile rank of 80 among all GPUs. The Radeon 8065S carries a 50th percentile ranking with no recorded benchmark scores, which places it in a different performance tier entirely. The NVIDIA part delivers a full suite of measurable results across OpenCL, Vulkan, DirectX iterations, and compute workloads, while the AMD part has no comparable data in the database. Buyers seeking verified performance should look at the RTX 5070 Ti Mobile. The Radeon 8065S targets a different use case, namely systems where the GPU shares system memory and relies on the host platform for bandwidth. The data indicates that the RTX 5070 Ti Mobile is the only one of the two with proven benchmark results, so any user needing those specific workloads should choose NVIDIA.

Architecture Differences

The two GPUs come from different foundries and process nodes. The AMD Radeon 8065S uses a 4 nm process at TSMC, while the NVIDIA GeForce RTX 5070 Ti Mobile uses a 5 nm process at the same foundry. The AMD chip, codenamed Gorgon Halo, is built on the RDNA 3.5 architecture and belongs to the Navi Mobile (RX 8000M) generation. The NVIDIA chip, GB205, uses the Blackwell 2.0 architecture and belongs to the GeForce 50 Mobile series. Die sizes differ meaningfully: AMD measures 308 mm², NVIDIA measures 263 mm². NVIDIA has disclosed transistor count at 31,100 million with a density of 118.3M per mm², while AMD's transistor count is listed as unknown.

Memory architecture is a major differentiator. The AMD Radeon 8065S uses system shared memory for both size and type, with a system dependent bandwidth and a memory clock tied to the host. The NVIDIA card has a dedicated 12 GB GDDR7 pool on a 192 bit bus, delivering 672.0 GB/s of bandwidth. This dedicated memory gives NVIDIA a substantial advantage in bandwidth-sensitive workloads. The AMD part has no separate VRAM, so it must compete for system memory bandwidth with the CPU and other components.

Core configurations also differ significantly. The AMD Radeon 8065S has 2,560 shading units, 160 texture mapping units, 64 render output units, and 40 ray tracing cores. The NVIDIA GeForce RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, 80 ROPs, 46 RT cores, and 184 tensor cores. NVIDIA's tensor core count is notable, as the AMD part lists no tensor cores at all. The NVIDIA GPU also has higher raw compute figures: 17.04 TFLOPS for FP32 and FP16, compared to 15.36 TFLOPS for both on the AMD side. Pixel and texture rates favor AMD, however, with the Radeon 8065S reaching 192.0 GPixel/s and 480.0 GTexel/s versus 115.8 GPixel/s and 266.2 GTexel/s for the RTX 5070 Ti Mobile.

Clock speeds show an interesting contrast. The AMD part has a base clock of 1295 MHz and a boost clock of 3000 MHz. The NVIDIA part has a lower base clock of 847 MHz and a boost clock of 1447 MHz. The AMD GPU compensates for fewer shading units with higher clocks and a different architecture, but the recorded benchmark data shows NVIDIA still wins overall. Power consumption is close: AMD lists 55 W TDP, NVIDIA lists 60 W TDP. Both are integrated GPUs with no power connectors and portable device dependent display outputs. Both support PCIe 5.0 x16, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Release timing differs by roughly ten months. The NVIDIA GeForce RTX 5070 Ti Mobile has a release date of 2025-02-28, while the AMD Radeon 8065S is dated 2025-12-31. The predecessor for AMD is listed as Polaris Mobile, and for NVIDIA it is GeForce 40 Mobile. Both are currently in Active production status.

Head-to-Head Benchmarks

The RTX 5070 Ti Mobile has nine recorded benchmark results, while the Radeon 8065S has none. This makes a direct comparison one-sided, but the available data still provides a clear picture. In Geekbench OpenCL, the NVIDIA card scores 143,870. In Geekbench Vulkan, it scores 139,213. These are the two highest individual scores in its benchmark suite. The PassMark tests show a range of results: DirectX 10 scores 151, DirectX 11 scores 237, DirectX 12 scores 102, and DirectX 9 scores 259. The G2D test scores 981, while the G3D test scores 24,004. The GPU compute test scores 10,101.

The average benchmark score for the RTX 5070 Ti Mobile is 35,435. This places it in the 80th percentile among all GPUs in the database. Its nearest rivals include the NVIDIA Quadro GV100 with an average score of 35,520 and a delta of -0.2%, meaning the Quadro is effectively tied. The AMD Radeon Pro Duo scores 35,860, which is 1.2% higher. The NVIDIA A2 scores 34,690, which is 2.1% lower. The NVIDIA T1000 scores 36,289, which is 2.4% higher. These deltas show that the RTX 5070 Ti Mobile sits in a competitive mid-range pack among professional and enterprise GPUs, with all four nearest rivals within roughly 2.5% of its score.

The AMD Radeon 8065S has no benchmark scores in the database, no average score, and no nearest rivals. Its percentile rank of 50 is a default placement rather than a measured result. This absence of data means the database cannot confirm any performance advantage for the AMD part. The architecture suggests strengths in pixel fill rate and texture rate, where the AMD GPU leads on paper, but no recorded benchmark validates those theoretical advantages. The head-to-head benchmark section is therefore dominated by the NVIDIA part, which has a full set of measurements across multiple test suites.

Where Each One Wins

The NVIDIA GeForce RTX 5070 Ti Mobile wins in every category with recorded data. It has the only benchmark scores in the comparison, the higher average score, the higher percentile rank, and the only dedicated memory subsystem. Its 12 GB of GDDR7 on a 192 bit bus with 672.0 GB/s bandwidth is a concrete advantage for any workload that depends on memory speed. Its 17.04 TFLOPS FP32 compute and 184 tensor cores make it suited for compute-heavy tasks such as AI inference, where tensor cores are essential. The nine recorded benchmarks cover OpenCL, Vulkan, DirectX 9 through 12, 2D, 3D, and compute workloads, giving it a verified profile across a wide range of applications.

The AMD Radeon 8065S wins in theoretical specifications only. It has a smaller process node at 4 nm versus 5 nm, a larger die at 308 mm² versus 263 mm², a higher boost clock at 3000 MHz versus 1447 MHz, and a significantly higher pixel rate at 192.0 GPixel/s versus 115.8 GPixel/s. Its texture rate of 480.0 GTexel/s is nearly double the NVIDIA part's 266.2 GTexel/s. These figures suggest the AMD GPU may have strengths in fill-rate limited scenarios, such as certain rasterization workloads, but no benchmark data confirms this. The AMD part also has a lower TDP at 55 W versus 60 W, which could indicate better efficiency in constrained thermal environments.

For users who prioritize verified performance across multiple test suites, the RTX 5070 Ti Mobile is the only choice with supporting data. Its nearest rivals in the database, the Quadro GV100, Radeon Pro Duo, A2, and T1000, all fall within 2.4% of its score, which places it in a well-defined competitive band. The AMD Radeon 8065S, by contrast, has no measured results and no rival comparisons, leaving its real-world behavior unquantified. The database shows that the NVIDIA part is the only one of the two with a complete performance record, and it uses that record to secure an 80th percentile ranking. The AMD part sits at the 50th percentile by default, which is not a measured outcome. In a direct comparison with the available data, NVIDIA wins all measured categories, while AMD offers only architectural specifications without verification.
