While AMD’s RDNA 2 architecture (codenamed “Navi 2x”) is generally excellent in terms of performance per watt, the smallest version of the GPU, the Navi 24, is severely underpowered in many departments. The GPU lacks some key capabilities such as media encoding and AV1 decoding. It’s also limited to just four PCIe lanes (x4) which means anything older than PCIe 4.0 hits it hard.
AMD has also introduced Navi 24 in desktops in the form of the RX 6500 XT and RX 6400. These are budget offerings and come with 4 gigs of VRAM which is simply not enough to compensate for the low PCIe bandwidth in case you run out of VRAM. And exceeding 4GB VRAM is relatively easy for 2022-23 AAA games where textures and other assets gobble it up quite easily. While AMD has since also launched an 8GB 6500 XT, its availability is a big question mark.
Now, after the RX 6500 XT and RX 6400, AMD may soon release another card in the Navi 24 family in the form of the RX 6300. Support for the new GPU has been added to TechPowerUp(TPU) GPU-Z recently version 2.52.0 . Alongside the AMD RX 6300, several new Nvidia GPUs were also listed.
While an entry-level gaming graphics card is certainly welcome as we haven’t had decent options since the AMD RX 550 and GT 1030 GDDR5, AMD Radeon RX 6300 is rumored to feature only 2GB of VRAM which means it could be a higher clocked version of the RX 6300M mobile GPU. If true, the 6300 would be by far the worst AMD or Nvidia card to launch in recent memory, as the 4GB VRAM is no longer enough due to the low PCIe bus width. On the other hand, a 4GB RX 6300 would be much better overall and the GPU could actually be decent for something of this caliber.
The latest GPU-Z also adds support for Nvidia’s RTX 4070 Ti, RTX 3080 Ti 20GB variant, RTX 3070 Ti (GA102), RTX 3050 (GA107), among others. You can download TechPowerUp GPU-Z 2.52.0 version here.
