AMD Radeon RX 470 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the NVIDIA GeForce RTX 5070 Ti Mobile across every shared benchmark. In Geekbench OpenCL, the RTX 5070 Ti Mobile scores 143,870 against the RX 470's 33,568, a 328.6% advantage. This is not a marginal lead; it is a generational chasm. The Vulkan test tells a similar story: 139,213 versus 39,884, translating to a 249% delta. Both figures place the RTX 5070 Ti Mobile in an entirely different performance tier.

The RX 470 does not win a single head-to-head test. Its highest recorded score in the database is 41,690 on Geekbench Metal, a test the RTX 5070 Ti Mobile does not appear in, so no direct comparison exists there. In the two tests where both GPUs ran identical workloads, the NVIDIA part leads by more than 3x in OpenCL and nearly 2.5x in Vulkan. The average benchmark score for the RTX 5070 Ti Mobile is 35,435, while the RX 470 averages 28,996, a 22.2% gap in aggregate. However, that aggregate number masks the extreme swings seen in individual tests, where the modern architecture dominates compute-heavy loads.

Looking at the nearest rivals for context, the RTX 5070 Ti Mobile sits within 2.4% of the NVIDIA T1000 (average score 36,289) and within 1.2% of the AMD Radeon Pro Duo (35,860). The RX 470, by contrast, lands within 0.7% of the AMD Radeon RX Vega M GH (29,197) and within 0.6% of the Intel Arc A370M (29,175). These rival clusters reinforce the point: the RTX 5070 Ti Mobile competes with professional and workstation-class parts, while the RX 470 aligns with mid-range mobile and small-form-factor GPUs.

Architecture Differences

The architectural gulf between these two GPUs is vast. The RTX 5070 Ti Mobile uses the GB205 chip built on TSMC's 5 nm process, packing 31,100 million transistors into a 263 mm² die. The RX 470 uses the Ellesmere chip on GlobalFoundries' 14 nm process, with 5,700 million transistors on a 232 mm² die. The transistor density tells the story: 118.3 million transistors per mm² for the NVIDIA part versus 24.6 million for the AMD part. That is a 4.8x density advantage, enabling far more compute resources in a similar physical footprint.

The memory subsystems are equally divergent. The RTX 5070 Ti Mobile ships with 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The RX 470 has 4 GB of GDDR5 on a 256-bit bus, providing 211.2 GB/s. Despite the narrower bus, the newer memory type gives the NVIDIA part 3.2x the bandwidth. Clock speeds also favor the NVIDIA part in effective terms: the RTX 5070 Ti Mobile runs at 847 MHz base and 1447 MHz boost with memory at 1750 MHz (28 Gbps effective), while the RX 470 runs at 926 MHz base and 1206 MHz boost with memory at 1650 MHz (6.6 Gbps effective). The higher boost clock on the NVIDIA part, combined with the massive memory bandwidth advantage, drives much of the performance gap.

Compute resources are not even close. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, and 80 ROPs. The RX 470 has 2,048 shading units, 128 TMUs, and 32 ROPs. The NVIDIA part also brings 46 RT cores and 184 tensor cores, features entirely absent from the RX 470, which has no dedicated ray tracing or tensor hardware. Pixel and texture rates reflect this: 115.8 GPixel/s and 266.2 GTexel/s for the RTX 5070 Ti Mobile versus 38.59 GPixel/s and 154.4 GTexel/s for the RX 470. FP32 throughput is 17.04 TFLOPS versus 4.940 TFLOPS, a 3.45x gap.

Power and connectivity further separate them. The RTX 5070 Ti Mobile has a 60 W TDP and is classified as an IGP (integrated graphics package) with no power connectors, designed for portable devices. The RX 470 has a 120 W TDP, takes a single 6-pin power connector, and requires a 300 W suggested PSU. The RX 470 is a dual-slot card measuring 240 mm in length, while the RTX 5070 Ti Mobile's dimensions are not recorded, as it is intended for mobile integration. Interface differences matter: PCIe 5.0 x16 for the NVIDIA part versus PCIe 3.0 x16 for the AMD part. API support also differs, with the RTX 5070 Ti Mobile supporting DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the RX 470 supports DirectX 12 (12_0) and Vulkan 1.3.

Where Each One Wins

The RTX 5070 Ti Mobile wins every scenario where compute throughput is the bottleneck. Its 17.04 TFLOPS FP32 performance, 672.0 GB/s bandwidth, and dedicated RT/tensor cores make it the clear choice for modern game engines with ray tracing, AI upscaling, or heavy compute shaders. The 12 GB VRAM also allows larger texture sets and higher resolution assets, while the RX 470's 4 GB is a hard limit for current AAA titles. For productivity workloads like GPU rendering, machine learning inference, or OpenCL compute, the 328.6% OpenCL lead is decisive.

The RX 470 holds one narrow advantage: power efficiency per watt in absolute terms is not listed, but the TDP figures suggest the AMD part uses twice the power (120 W) to deliver a fraction of the performance. That is not a win; it is a liability. However, the RX 470 does have a functional niche in legacy environments. It supports DirectX 12 (12_0) and Vulkan 1.3, which covers most older games and lightweight productivity apps. Its 4 GB VRAM is sufficient for 1080p esports titles from its era. Its 38.59 GPixel/s pixel fill rate and 154.4 GTexel/s texture rate are adequate for simple 2D or low-poly workloads. For a desktop system with a 300 W PSU and a 6-pin connector, the RX 470 remains a working, if dated, option.

The RTX 5070 Ti Mobile also wins on portability. Its IGP classification and 60 W TDP mean it can be integrated into thin laptops, while the RX 470 requires a full dual-slot chassis. The NVIDIA part supports PCIe 5.0 x16, which future-proofs bandwidth for external GPU docks or high-speed storage, whereas the RX 470 tops out at PCIe 3.0. The display outputs differ too: the RX 470 has fixed ports (1x HDMI 2.0b, 3x DisplayPort 1.4a), while the RTX 5070 Ti Mobile's outputs are portable-device-dependent, offering flexibility in laptop designs.
