To bad this 5300m isn't more like the one Apple is using, which has the full 128bit and only loses 2CU. I'd rather lose 10% of the processing hardware than 25% of the bandwidth and VRAM.
Since Nvidia has pretty much been the default mobile GPU, I wonder where the 5300M competes. If it's worse than the mobile 1050 3GB (not even 1650) it's really worthless. I was really hoping there wouldn't be anything lower than that in Nvidia's lineup (like they had with the 940MX previously), but then they dropped the MX150 (now MX250).
If you really need more than IGP performance, then the bare minimum DGPU shouldn't be lower than low end. Personally I feel like the bare minimum VRAM should be 4GB as well, with 1080p being the minimum screen resolution for laptops.
One would hope that TDP is lower by quite a bit. The 85W that the RX5500M needs would demand considerable cooling and power making using it without plugging into a wall outlet with a fairly large power supply a difficult prospect. I guess it doesn't really matter much to anyone as long as the RX 5300M remains an Apple only GPU since it will not ship in significant numbers.
Are the ROPs count right? Are those usually tied to the memory controller and the number of memory channels? Offhand I'd have expected it to drop down to 24 ROPs.
The only mobile Navi 14 part to currently come with an 8GB option is the Radeon Pro 5500M, which is otherwise identical spec-wise to the 4GB model. The RX 5500M is 4GB only atm.
Thanks, makes sense. Do we have information on the Pros then? Are they otherwise identical, aside from memory and presumably the Pro 5300M having the greater memory bus as well?
On Apple's configurator, the Radeon Pro 5300M is stated as having 20 CUs, while the Radeon Pro 5500M is listed as having 24 CUs. The Radeon Pro models are entirely different SKUs.
It should be noted that the 16" MacBook Pro isn't using either of the RX 5300M or RX 5500M SKUs in this article. The Radeon Pro 5300M and Radeon Pro 5500M have 20 and 24 CUs respectively, compared to the 22 CUs of both the Radeon RX 5300M and Radeon RX 5500M, among other differences such as memory bus width and configured VRAM capacity.

Too bad memory clocks are already pretty high at 14gbps, since with a huge memory overclock it could catch up with the 5500m.EliteRetard - Wednesday, November 13, 2019 - link

Apple isn't using the RX 5300M.... They are using the completely unrelated Radeon Pro 5300M, which is totally different spec-wise.PeachNCream - Thursday, November 14, 2019 - link
Oh thanks! I misunderstood that portion of the artcile while reading it the first time around.kpb321 - Wednesday, November 13, 2019 - link

Probably using a crossbar which allows for the mismatch.extide - Wednesday, November 13, 2019 - link
On Nvidia GPU's yes, they are tied together -- AMD does not have that limitation.casperes1996 - Wednesday, November 13, 2019 - link
What about the 8GB variant of the 5500M?Cooe - Wednesday, November 13, 2019 - link

On Apple’s website, it says the 5300M has 4GB of VRAM. There’s a discrepancy here, what gives?Ryan Smith - Wednesday, November 13, 2019 - link
They are different SKUs. This is the Radeon RX 5300M. Apple has the Radeon Pro 5300M.casperes1996 - Friday, November 15, 2019 - link

looks like apple is also unique in getting a fully enabled 24CU 5500 sku.everyone else gets 22CU's.
