Integrated graphics solutions are becoming vital part of laptop user’s daily life. Intel and AMD have never failed to surprise us in integrated graphics department since Ryzen Raven Ridge and Ice Lake chips based laptops hit the market to provide much improved visual performance not only in 2D office tasks but also in lite gaming.
Both chip making giants have accomplished major achievements in iGPU implementations including eliminating memory bandwidth bottlenecks due to DDR4 RAM’s gradual perfection process. However, AMD APU iGPUs are always faster than Intel ones.
Thanks to patented Radeon Vega integrated graphics of AMD with up to 10 Compute Units (CUs) for 12nm Picasso APUs and up to 8 CUs for latest 7nm Renoir APUs. On the other hand, Intel has a flagship Ice Lake Core i7-1065G7 with Iris Plus Graphics with decent performance beating the Vega 8 (12nm) Picasso APUs in some gaming benchmarks. But today, prominent YouTuber TechEpiphany has done a tremendous effort by comparing Intel Iris Plus Graphics against both 12nm Vega 10 and 7nm Vega 7 iGPUs in playing triple A heavy game title Resident Evil 2.
Amazing 10% higher FPS performance shown by 7nm Renoir Radeon Vega 7 (CUs) against it’s 12nm RX Vega 10 (CUs). Really it is 7nm process and some graphics architecture changes are helping Vega 7 to upbeat the Vega 10 even though later one has 3 more graphics CUs. Graphics memory usage of Vega 7 is shockingly lower than it’s two counterparts, perhaps, it’s utilizing higher memory clock speed. All three iGPUs successfully utilized Dual Channel RAM for each laptop’s own configuration. Unfortunately, Ryzen 7 3700U was choked by 2400MHz RAM speed that been set up by laptop manufacturer, yet the speed doesn’t change regardless you add higher RAM speed stick because first SODIMM slot is soldered to laptop motherboard.
In contrast, Intel Iris Plus Graphics delivers much playable performance above 40 fps but 25% slower than the latest Renoir’s Vega 7 iGPU. Indeed, for clear and fair results, reviewer has made sure that i7-1065G7 and Ryzen 7 3700U weren’t throttled by mediocre laptop thermals by limiting all machines running at 20-22W TDP. For the Vega 7 iGPU, TechEpiphany has chosen Ryzen 7 4800HS APU which has a far superior thermal design heatsink within ASUS ROG Zephyrus G15 gaming laptop. Hope you enjoy these performance comparisons of APUs and Integrated Graphics. As soon as, DDR5 SODIMM RAM hits the market, Intel and AMD will dominate entry level or esports gaming segment with higher memory bandwidth and speed.
