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.

I would have been happier if they had just knocked another $50 off of the existing Radeon RX 5500 boards, but maybe there are enough partially-defective Navi 14 chips to make this new SKU worthwhile.

I'm definitely going to be interested in this (or a lesser model), if the price is right.

Makes sense, AMD needs a 75W product that maximises GPU performance without requiring additional power connectors to keep OEMs happy.

The quiet HTPC crowd won't be displeased, either.

YES!!! More low-profile and single-slot cards, please!

Wonder what price will be and if there will be a 6GB configuration. If the 75w power draw is right they could be rather interesting given it's PCIe 4.0. If would be cool if the were CF capable and the scaling was great. That power draw and cheap entry price point would make for a intriguing 2-way/3-way/4-way CF modular upgrade pathway if scaling is better and/or more reliable for PCIe 4.0 and DX12. I'm not expecting that, but would be a interesting little twist.

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.

Unlikely, Navi 14 only has a 128-bit memory interface so expect 4GB at most.

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.

Not sure if you are aware that there are 8GB versions of RX 5500 out in the market. And you don't need 192bit to support 6GB. 96bit in this case will be able to run 6GB. It just whether card manufacturers will actually offer a 6GB version due to cost and power restrictions.

Ignore me, I was having a brainfart thinking this was cut down further than it was. This is just harvesting Navi 14 dies with a defective memory controller.

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.

96-bit memory bus will be a trade-off capacity for actual speed.
