The TLDR
The charts above outline the geometric mean of our suite of integrated graphics tests at both 1920x1080 (FHD) and 1280x720 resolutions. Here we're testing with the RX Vega graphics on the Ryzen 7 4750G and Ryzen 5 3400G against the UHD Graphics 630 engine onboard the Core i7-10700K.
We subbed in the 10700K for these tests because even though the 4750G competes with the non-K 10700, we only have the graphics-less 10700F for comparison (we use the 10700F in the remainder of our tests on the following pages).
The Core i7-10700K is faster and falls into a higher price bracket than the 10700, but that's hardly an advantage: The Ryzen 7 4750G provides roughly three times as much performance with the tested FHD and 1280x720 games, and that's at stock settings. After overclocking the 4750G's CPU to 4.45 GHz, the memory to DDR4-4000, and the iGPU to 2400 MHz, Renoir stretches that advantage to roughly 3.5X.
However, the 4750G's gains against the previous-gen Ryzen 5 3400G aren't as pronounced, but they are impressive given that the Renoir chips has three fewer CUs. The 4750G's Vega graphics enjoy improved clock rates and higher memory throughput than the 3400G, yielding 13% more performance with FHD and roughly ~2.5% more performance at 1280x720 (stock settings).
As a general statement, the stock Ryzen 7 4750G basically provides a bit more performance than the overclocked Ryzen 5 3400G, but the gap widens when we compare the two chips with overclocked settings. The tuned 4750G beats the OC'd 3400G by 23% at the FHD resolution, and by 20% at 1280x720. That's a nice step forward if you're willing to invest in the components, like a capable cooler and memory kit, though that could be a bit pricey for this class of chip. Memory bandwidth still appears the be the limiting factor in our tests, but its noteworthy that higher memory overclocks do tend to reach a diminishing point of returns.
Civilization VI on AMD Ryzen 7 Pro 4750G iGPU
The following albums contain test results of both FHD and 1280X720 resolutions (except for World of Tanks). Both of our Ryzen 7 Pro 4750G configurations suffered from a few outliers during the Civilization VI benchmark, which registers as spikes in our frame rate chart and reduced 99.9th percentile frame rates. These spikes weren't noticeable during the benchmark, and the less-granular 99th percentile measurements are slightly better than the Ryzen 5 3400G. Overclocking is a real boon for the 4750G - here we can see it take a substantial lead after tuning.
Far Cry 5 on AMD Ryzen 7 Pro 4750G iGPU
We encountered a few interesting results with the Ryzen 7 Pro 4750G during the Far Cry 5 benchmark. As you can see in the FHD results, the stock 4750G provides lower 99th percentile frame rates than the overclocked 3400G, and that same trend persisted after overclocking. We re-ran these tests multiple times, even dialing back the overclocked iGPU, but encountered identical results. This could be the result of a driver or unoptimized game engine, but the results aren't devastating to performance - the chip is still much faster overall than the 3400G and beats the 10700K by leaps and bounds. In fact, through some portions of this test, the 10700K is like watching a slideshow.
Shadow of the Tomb Raider on Ryzen 7 Pro 4750G iGPU
The Ryzen 7 Pro 4750G again tops the charts in this title as it delivers a fast, smooth gaming experience. We continue to see a few outliers in our very-granular 99.9th percentile measurements (last two slides), but these don't seem problematic during gameplay. We suspect that driver optimizations could iron out these wrinkles.
Strange Brigade on Ryzen 7 Pro 4750G iGPU
World of Tanks: Encore on Ryzen 7 Pro 4750G iGPU
The World of Tanks Encore benchmark finds the Ryzen 7 4750G capping our integrated graphics benchmark with much the same trend we've seen throughout our tests: At stock settings, the 4750G performs much like the overclocked Ryzen 5 3400G, but separates itself from the pack after overclocking.
Overall the Ryzen 7 4750G is at least a decent step forward over the Ryzen 5 3400G, but we don't see the types of improvements that could be had with a new graphics architecture, and the graphics engine is obviously hampered by memory throughput.
However, the chip does support passable 1080p framerates for the most budget of gaming systems, but you'll have to use lowered quality settings and a narrower cross-section of games, all of which are expected in this price class.
