Where Each One Wins

The recorded data shows a clear split between the two parts. The NVIDIA GeForce RTX 3070 Ti Mobile dominates in compute workloads. In Geekbench OpenCL, it posts a score of 106,022 compared to the AMD Radeon 860M's 22,759, a 78.5% advantage. In Geekbench Vulkan, the NVIDIA part scores 100,027 versus 30,043 for the AMD part, a 70% lead.

The AMD Radeon 860M wins on efficiency and integration. Its 15 W TDP is dramatically lower than the NVIDIA part's 115 W, and it is built into the processor as an IGP with no power connectors required. This makes it suitable for thin-and-light portable devices where the NVIDIA part's power budget would be prohibitive.

The AMD Radeon 860M also wins on overall benchmark standing. Its average score of 26,401 places it in the 72nd percentile of all GPUs, while the NVIDIA part's 23,518 average places it in the 69th percentile. This is notable because the AMD part achieves this with far fewer shading units and much lower power consumption.

For legacy API coverage, the NVIDIA GeForce RTX 3070 Ti Mobile has additional PassMark scores across DirectX 9, 10, 11, and 12, plus G2D, G3D, and GPU compute tests. The AMD Radeon 860M has no recorded PassMark results in the database, so its behavior in those specific legacy workloads is not measured here.

Architecture Differences

The AMD Radeon 860M uses the Krackan Point chip built on RDNA 3.5 architecture, fabricated by TSMC on a 4 nm process. It belongs to the Navi III IGP generation for Strix Point Mobile. The NVIDIA GeForce RTX 3070 Ti Mobile uses the GA104 chip on Ampere architecture, fabricated by Samsung on an 8 nm process, and belongs to the GeForce 30 Mobile generation.

Transistor counts differ substantially. The NVIDIA part contains 17,400 million transistors on a 392 mm² die, with a transistor density of 44.4M per mm². The AMD part's transistor count and die size are unknown in the database.

The RT core counts differ: the AMD Radeon 860M has 8 RT cores, while the NVIDIA GeForce RTX 3070 Ti Mobile has 46 RT cores. The NVIDIA part also includes 184 tensor cores, a feature entirely absent from the AMD IGP.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD part uses a PCIe 4.0 x8 bus interface, while the NVIDIA part uses PCIe 4.0 x16.

The AMD Radeon 860M has a base clock of 600 MHz and a boost clock of 3000 MHz. The NVIDIA GeForce RTX 3070 Ti Mobile has a base clock of 915 MHz and a boost clock of 1410 MHz, with memory clocked at 1750 MHz or 14 Gbps effective.

Specification Differences

The shading unit count is the largest specification gap. The AMD Radeon 860M has 512 shading units, while the NVIDIA GeForce RTX 3070 Ti Mobile has 5,888, which is 11.5 times more. Texture mapping units differ similarly: 32 for AMD versus 184 for NVIDIA. Render output units are 16 for AMD and 96 for NVIDIA.

Compute throughput reflects these differences. The AMD Radeon 860M delivers 3.072 TFLOPS of FP32 and FP16 (1:1). The NVIDIA GeForce RTX 3070 Ti Mobile delivers 16.60 TFLOPS of FP32 and FP16 (1:1), roughly 5.4 times higher.

Pixel and texture rates follow the same pattern. The AMD part achieves 48.00 GPixel/s and 96.00 GTexel/s. The NVIDIA part achieves 135.4 GPixel/s and 259.4 GTexel/s.

Memory is a fundamental difference. The AMD Radeon 860M uses system shared memory with system dependent bandwidth. The NVIDIA GeForce RTX 3070 Ti Mobile has dedicated 8 GB GDDR6 on a 256-bit bus with 448.0 GB/s bandwidth.

Power requirements diverge sharply. The AMD Radeon 860M is rated at 15 W TDP and is an IGP with no power connectors. The NVIDIA GeForce RTX 3070 Ti Mobile is rated at 115 W TDP and also lists no power connectors, meaning it relies on the laptop's internal power delivery.

The process node difference is notable: 4 nm for AMD versus 8 nm for NVIDIA. This partially explains how the AMD part achieves meaningful performance at 15 W.

Head-to-Head Benchmarks

The database records two direct comparisons between these GPUs. Both come from Geekbench tests, and both go to the NVIDIA GeForce RTX 3070 Ti Mobile.

In Geekbench OpenCL, the NVIDIA part scores 106,022 against the AMD Radeon 860M's 22,759. The delta percentage is 78.5% in favor of NVIDIA. This is the larger margin of the two tests, and it aligns with the raw compute specification gap: 16.60 TFLOPS versus 3.072 TFLOPS.

In Geekbench Vulkan, the NVIDIA part scores 100,027 against the AMD Radeon 860M's 30,043. The delta percentage is 70% in favor of NVIDIA. The AMD part performs relatively better in Vulkan than in OpenCL, but the NVIDIA part still holds a commanding lead.

The NVIDIA GeForce RTX 3070 Ti Mobile wins both head-to-head tests, giving it 2 wins in the recorded comparisons. The AMD Radeon 860M has 0 wins.

Looking at the wider benchmark picture, the AMD Radeon 860M's average score of 26,401 actually exceeds the NVIDIA part's average of 23,518, despite losing both direct comparisons. This is because the NVIDIA part's average includes several PassMark tests with lower scores, including 124 in DirectX 10, 153 in DirectX 11, 73 in DirectX 12, and 196 in DirectX 9. These legacy API results drag down the NVIDIA average.

The AMD Radeon 860M's nearest rival is the NVIDIA GeForce MX550 at 26,421, which is essentially a tie at 0.1% difference. The NVIDIA GeForce RTX 3070 Ti Mobile's nearest rival is the NVIDIA GeForce RTX 3080 Mobile at 23,628, a 0.5% difference.

The Verdict

The data supports a straightforward choice for compute-heavy workloads. The NVIDIA GeForce RTX 3070 Ti Mobile is decisively faster in both recorded benchmarks, with 78.5% and 70% margins in OpenCL and Vulkan respectively. Its 5,888 shading units, 184 tensor cores, 46 RT cores, and 448.0 GB/s of dedicated bandwidth make it the clear pick for tasks that stress raw GPU throughput.

The AMD Radeon 860M is the pick for constrained power envelopes. Its 15 W TDP is a fraction of the NVIDIA part's 115 W, and it requires no power connectors. This makes it the only realistic option for ultraportable devices where the NVIDIA part simply cannot fit thermally or electrically.

For overall percentile ranking, the AMD Radeon 860M actually sits higher at the 72nd percentile versus the NVIDIA part's 69th percentile. Its average benchmark score of 26,401 beats the NVIDIA part's 23,518 average. This is a peculiar result driven by the NVIDIA part's weak legacy DirectX scores in PassMark.

Buyers who prioritize modern compute performance and have the power budget should choose the NVIDIA GeForce RTX 3070 Ti Mobile. The data shows it is vastly faster in the two direct tests recorded, and its dedicated memory subsystem with 448.0 GB/s bandwidth is a major advantage.

Buyers who need integrated graphics in a low-power system should choose the AMD Radeon 860M. The data shows it delivers respectable compute scores, ranking in the 72nd percentile of all GPUs, while consuming only 15 W. Its 4 nm process and RDNA 3.5 architecture allow it to compete with much larger discrete parts on a per-watt basis.

The AMD Radeon 860M is also the only one of the two that is still in production. The NVIDIA GeForce RTX 3070 Ti Mobile is end-of-life. For new designs, this favors the AMD part regardless of raw performance.
