The GPU holds the 73rd percentile among all GPUs, while the CPU ranks in the 78th percentile, indicating a well-matched mobile platform where neither component dramatically overshadows the other.

GPU Analysis — VRAM, bandwidth, clocks, RT/tensor hardware, what the benchmark scores mean for rendering

The NVIDIA GeForce RTX 4070 Mobile is built on the Ada Lovelace architecture using TSMC's 5 nm process, packing 22,900 million transistors on a 188 mm² die. The GPU features 8 GB of GDDR6 memory on a 128-bit bus, delivering 256.0 GB/s of memory bandwidth. This memory configuration is adequate for 1080p gaming and most 1440p titles, though the 8 GB capacity may become a limiting factor in future titles with heavy texture requirements. The memory clock runs at 2000 MHz with 16 Gbps effective data rate.

Clock speeds are set at a 1395 MHz base and 1695 MHz boost, which is conservative for a mobile RTX 4070-class part. The GPU's compute resources are substantial: 4608 shading units, 144 texture mapping units, and 48 raster operation pipelines. More importantly for modern workloads, the RTX 4070 Mobile includes 36 dedicated RT cores and 144 tensor cores. The RT cores enable hardware-accelerated ray tracing, while the tensor cores accelerate DLSS and other AI-based rendering techniques. The FP32 throughput of 15.62 TFLOPS, with FP16 running at the same rate (1:1), indicates strong raw compute capability for both gaming and compute workloads.

Build Overview

This build pairs the AMD Ryzen 5 8640U mobile processor with the NVIDIA GeForce RTX 4070 Mobile GPU in a laptop form factor, as indicated by the buildClass of "laptop". The CPU is a 6-core, 12-thread Zen 4 part with a 28 W TDP, while the GPU is an Ada Lovelace architecture part with a 115 W TDP. The combined percentile ranking of 76 places this system in the upper quarter of all benchmarked CPU+GPU combinations, indicating a high-performance laptop configuration.

The CPU's 78th percentile ranking and the GPU's 73rd percentile ranking show a well-matched pairing. The CPU's average benchmark score of 26462 and the GPU's average benchmark score of 27435 are very close, suggesting that neither component dramatically outclasses the other. This balance makes the system versatile across a wide range of workloads, from gaming to content creation to productivity. The laptop class means this performance is delivered in a portable form factor, though the combined TDP of 143 W (28 W CPU + 115 W GPU) indicates that battery life under load will be limited.

Upgrade Path and Platform

The Ryzen 5 8640U uses the AMD Socket FP8 and supports DDR5 memory with dual-channel configuration, providing 89.6 GB/s of memory bandwidth. The CPU supports PCIe Gen 4 with 20 lanes, which provides sufficient bandwidth for the RTX 4070 Mobile's PCIe 4.0 x8 interface and NVMe storage. The platform does not support ECC memory, and the CPU has a locked multiplier, so overclocking is not possible. The GPU has no power connectors (slot width is IGP), and no suggested PSU is listed, which is typical for a laptop configuration where power delivery is handled by the system's power brick.

For memory upgrades, the DDR5 support means users can increase RAM capacity, though the dual-channel configuration means adding memory in pairs is optimal for bandwidth. The CPU's 16 MB L3 cache is shared across all cores, and the 89.6 GB/s memory bandwidth is sufficient for the CPU's needs, but the GPU's 256.0 GB/s bandwidth is separate and cannot be upgraded.

A sensible next upgrade for this platform would be increasing the system's RAM capacity, as DDR5 memory is supported and the CPU's performance scales with available memory bandwidth. The PCIe Gen 4 support with 20 lanes means users can add fast NVMe storage for improved load times and data access. However, the laptop form factor and the integrated nature of the GPU mean that GPU upgrades are not possible — the RTX 4070 Mobile is soldered to the motherboard. The CPU is also not upgradeable in most laptop configurations, as the Socket FP8 is typically BGA (ball grid array) soldered. Therefore, the primary upgrade path is memory and storage, while the CPU and GPU are fixed for the life of the laptop.
