AMD Radeon 620 vs NVIDIA GeForce RTX 3070 Mobile
Comparison of graphics card architecture, market segment, value for money and other general parameters.
General performance parameters such as number of shaders, GPU core clock speeds, manufacturing process, texturing and calculation speed. These parameters indirectly speak of performance, but for precise assessment you have to consider their benchmark and gaming test results.
Compatibility, dimensions and requirements
Information on Radeon 620 and GeForce RTX 3070 Mobile compatibility with other computer components. Useful when choosing a future computer configuration or upgrading an existing one. For notebook video cards it's notebook size, connection slot and bus, if the video card is inserted into a slot instead of being soldered to the notebook motherboard.
Parameters of memory installed: its type, size, bus, clock and resulting bandwidth. Note that GPUs integrated into processors don't have dedicated memory and use a shared part of system RAM.
Video outputs and ports
Types and number of video connectors present on the reviewed GPUs. As a rule, data in this section is precise only for desktop reference ones. OEM manufacturers may change the number and type of output ports, while for notebook cards availability of certain video outputs ports depends on the laptop model rather than on the card itself.
APIs supported, including particular versions of those APIs.
Non-gaming benchmark performance comparison. Note that overall benchmark performance is measured in points in 0-100 range.
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.
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.
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 Discontinued and later superceded by Vulkan)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.
