AMD Radeon RX 5300 (Desktop) Surfaces on Geekbench
AMD is coming around to launching its entry-level Radeon RX 5300 on the desktop platform, although it remains to be seen if the SKU will be released in the AIB (all-in-board) retail channel, or remains an OEM-exclusive. It surfaced an "AMD 7340:CF" graphics device on the Geekbench database, and was identified as the RX 5300 (non-mobile) by Komachi Ensaka. The OpenCL benchmark component of Geekbench identifies the card as having 24 compute units (1536 stream processors). The mobile RX 5300M has 3 GB of GDDR6 memory across a 96-bit wide memory bus, and the desktop RX 5300 appears to have the same memory configuration. The SKU hence appears to be based on the 7 nm "Navi 14" silicon, the same one that powers the RX 5500 series.

The quiet HTPC crowd won't be displeased, either.
As a aside note if AMD in the future used it HBCC with CF setups and they could raid M.2 cache drives along with more or less scaling performance close to double that would be interesting as well. On another note because of DX12 works with mGPU now they could get away with less VRAM capacity potentially, but even otherwise with the HBCC and M.2 cards they could somewhat especially in these mGPU setup scenario's if they utilized the M.2 cards in a raid setup. That bridge AMD used for the new Radeon Pro's comes to mind as well very fast infinity fabric interconnect would be perfect for a HBCC M.2 raid between cards along with gobs of bandwidth scaring between the cards. AMD just needs a infinity fabric bridge that can handle the bandwidth of like one of those quad M.2 raid-0 card like Asrock has where it draws from a M.2 slot on additional cards to jointly pool resources together. It would be more interesting with a CPU and LPDDR4 ram slot as well, but oh well maybe eventually we'll get that modular CF APU setup that can be 2-way/3-way/4-way and scale near linearly.
6GB would require 192-bit and only happens on the 5600 because that's using a cut down Navi 10 die with 256-bit memory interface originally.
I doubt there will be an 8GB variant because on a 128-bit interface that needs more expensive, higher-density GDDR6 BGA packages and this is a budget card where that would defeat the purpose of the product.
It does tolerably well at 1080p. It should serve my senior citizen mother well.
We might see 6GB variants but I wouldn't get your hopes up - this is going to be defective silicon running at lower clocks to hit a lower price point. The last thing vendors will want to do is put double-density GDDR6 on a product like that to jack up the price into 1650 Super territory and cannibalise their RX5500 line.
Not saying it can't happen, just that it probably wont.
