The RX Vega 56 wins decisively in texture throughput at 329.5 GTexel/s, which is 23.8% faster than the RTX 5070 Ti Mobile's 266.2 GTexel/s. This is driven by its 224 TMUs versus 184, despite the NVIDIA part having more shading units (5888 versus 3584). The AMD card also holds a higher pixel rate per ROP, with 64 ROPs delivering 94.14 GPixel/s, while the RTX 5070 Ti Mobile's 80 ROPs deliver 115.8 GPixel/s—meaning the AMD part achieves 1.47 GPixel/s per ROP versus 1.45 for NVIDIA, a negligible per-unit difference. In aggregate benchmarks, the RX Vega 56's average score of 37507 tops the RTX 5070 Ti Mobile's 35435, and its nearest rival deltas are tighter: the RX Vega 56 sits within 1.6% of the RTX 4080 Mobile, while the RTX 5070 Ti Mobile trails the T1000 by 2.4%.

Architecture Differences

The architectural gap is stark: the RX Vega 56 uses the Vega 10 chip on GCN 5.0 architecture, built on a 14 nm process at GlobalFoundries, while the RTX 5070 Ti Mobile uses the GB205 chip on Blackwell 2.0, fabricated on TSMC's 5 nm node. The RX Vega 56 integrates 12,500 million transistors across a 495 mm² die, yielding a density of 25.3M transistors per mm². The RTX 5070 Ti Mobile packs 31,100 million transistors into a 263 mm² die, achieving 118.3M per mm²—a 4.7x density advantage and a 46.9% smaller die despite 2.5x more transistors.

The shader configuration differs fundamentally: the RX Vega 56 has 3584 shading units, 224 TMUs, and 64 ROPs, while the RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, and 80 ROPs. The NVIDIA part adds 46 RT cores and 184 tensor cores, which the AMD card lacks entirely. Memory architecture is another differentiator: the RX Vega 56 uses 8 GB HBM2 on a 2048-bit bus, while the RTX 5070 Ti Mobile uses 12 GB GDDR7 on a 192-bit bus. The AMD card's wider bus compensates for slower memory clocks (800 MHz / 1600 Mbps effective versus 1750 MHz / 28 Gbps effective), but the NVIDIA part still achieves 64.1% more bandwidth.

API support favors the RTX 5070 Ti Mobile with DirectX 12 Ultimate (12_2) and Vulkan 1.4, versus DirectX 12 (12_1) and Vulkan 1.3 on the RX Vega 56. Both support OpenGL 4.6. The power envelope is dramatically different: the RX Vega 56 consumes 210 W with dual-slot cooling and 2x 8-pin connectors, while the RTX 5070 Ti Mobile is an integrated graphics processor (IGP) at 60 W with no power connectors. The RX Vega 56 requires a 550 W PSU; the RTX 5070 Ti Mobile lists none.
