Benchmark performance

Non-gaming benchmark performance comparison. Note that overall benchmark performance is measured in points in 0-100 range.

Overall score

This is our combined benchmark performance rating. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.

Radeon 620 0.74
RTX 3070 Mobile 25.93 +3404.1%

3DMark Fire Strike Graphics

Fire Strike is a DirectX 11 benchmark for gaming PCs. It features two separate tests displaying a fight between a humanoid and a fiery creature seemingly made of lava. Using 1920x1080 resolution, Fire Strike shows off some realistic enough graphics and is quite taxing on hardware.

Gaming performance

Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.

Advantages of AMD Radeon 620

Mantle (an API developed by AMD for 3D graphics acceleration. Discontinued and later superceded by Vulkan)

Vulkan (a contemporary API for graphics acceleration, based on now-discontinued Mantle)

Advantages of NVIDIA GeForce RTX 3070 Mobile

3404.1% faster (about 35 times) in synthetic tests

Much newer (4 January 2021 vs 12 August 2019)

Wider memory bus (256 vs 64 bit)

More pipelines (5120 vs 384)

Finer manufacturing process technology (8 vs 28 nm)

So, 620 or RTX 3070 Mobile?

Judging by the results of synthetic and gaming tests, Technical City recommends NVIDIA GeForce RTX 3070 Mobile, since it shows better performance.
