AMD Radeon RX 5700 XT and RX 5700 to Have Same Memory and ROP Configuration

In a bid to bolster competitiveness of the $379 Radeon RX 5700 (non-XT) against its rival from the NVIDIA camp, the GeForce RTX 2060, AMD is leaving the memory configuration completely unchanged from the faster $449 Radeon RX 5700 XT. The RX 5700 will get 8 GB of GDDR6 memory across a 256-bit wide memory bus, with the same 14 Gbps memory speed as the RX 5700 XT. This works out to a memory bandwidth of 448 GB/s. In comparison, the $349 (launch price) RTX 2060 only has 6 GB of memory, across a 192-bit wide memory bus. With a memory speed of 14 Gbps, this setup achieves 336 GB/s.

The other area where AMD is reinforcing the RX 5700 is its raster muscle. The RX 5700 has the same 64 ROPs as the RX 5700 XT. AMD carved this SKU out by disabling two workgroup processors (four RDNA compute units), reducing the stream processor count to 2,304. This also turns down the TMU count from 160 to 144. The GPU engine clock speeds are also reduced, with 1465 MHz base, 1625 MHz "gaming clocks," and 1725 MHz boost clocks; compared to 1605/1755/1905 MHz of the RX 5700 XT. The RX 5700 has a typical board power of 180W compared to the 224W of the RX 5700 XT. Custom design cards may even feature just one 8-pin PCIe power input, while some of the premium factory-overclocked designs could use 8-pin + 6-pin configurations.

Interesting to see if we could use 5700XT 50th Anniversary Bios on the RX 5700 and get great value from 380$.
Did same with RX 470 Nitro with RX 580 Nitro bios, worked great.

"Custom design cards may even feature just one 8-pin PCIe power input, while some of the premium factory-overclocked designs could use 8-pin + 6-pin configurations "
and the reference comes with 2x8pin? sounds quite power hungry for a mid-high end card.

The RX 5700 has no real reference card AFAIK. It's a partner-driven launch. The cheaper cards could have single 8-pin, the pricier ones could have 8+6-pin.

They learned their PCIe lesson.

The real question is if we can mod the bios to unlock these.

From what I understand of BIOS, yes you can unlock the BIOS, but I don't think it will be for everyone as it looks like it will need some kind of physical modification to the card to unlock it. Here I have come across lock SPD, but to save time I just copy & soldered in a new SPD. BIOS I do believe are locked in a similar way.

Most likely.

The real question here is, if whether or not the difference will be in software level, so anybody can modify bios or hardware level, you cant do anything to circumvent it.

Price wise they are very close, $379 x $449, whether will be worth or not remains to be seen. So far the difference in performance is 20%. So is it worth the extra $70 for 20% more performance, I'd say yes because every 10% is worth $38 usd and 20% is $76, so the 5700 xt price is justified.

I hope that they also have a 60-70CU variant of this chip, that will be called 5800XT. It could be in the 450mm^2 range, but they can at least try to fight 2080Ti.

I'm against how amd named this time unless they justify the 5800 to be very agressive in a bid to x 2080, I mean I like the 5700 nomenclature, but hate this thing in front of it, "xt" and non xt, rx 470 and rx 480 was good. The xt and non xt confuses people, 5750, 5770 and 5790 would have made more sense.

Great value imho for this variant of Navi, especially after 2-3 months since I think the price will fall closer to $300 and we will have custom cooler ones available from the start.

You can likely flash the XT bios and get a great value card that is +/- 2070 when max oc'd.
Might if it works.

I still believe that this small silicon has great potential- same as old OC friendly 980Ti.
It was designed from start for TSMC's 7nm with High clocks in mind,so I don't believe it can't OC at least as good as Radeon VII, so with good cooling and AIB big coolers we gonna see 5700XT competing at RTX 2080 league after OC, so the price will be more competitive for users who like to play with their GPU [like Vega56->64].
AMD claims that even with "Gaming clocks" it should be around 10% better then RTX 2070- so with nice OC headroom the RTX 2080 not so far away:
I hope I am not wrong- because then Nvidia gonna milk us even more :-(.

VBIOS is locked and PowerPlay table is removed. Go read some post launch articles. This gen chips from red camp is heavily locked down in terms of modifications.

Maybe if it will be needed then somehow Unlock methods will be found and many articles will pop out - great for PR :-).

I honestly doubt you'll get that extra 12-15% out to match 2080.
Now, I already see people bringing up Anniversary Edition if it has better binned silicon and swapping coolers on them afterwards - yeah, but that's another $ above its 500$ price point, at which point I honestly don't see why anyone should bother instead of, like, just getting the 2080.
The XT is quite possibly good for what it is - a 2070 alternative if you don't care about basic DXR features like reflections and GI that are getting available across different games. Expecting more than that is, unfortunately, wishful thinking IMO.

Vega is locked, you can still flash compatible bios.
Since its the same chip it will likely work

We had to learn on so many card how to circumvent limits, no reason this will be impossible, other than yields, if the yield is lower than a certain threshold the chips have a high chance of defects on the die.

So The 5700XT 50th UN is 235W vs 225W for regular 5700XT, we need to get it's bios and test on 5700/5700XT, Lets hope it's gonna be possible.
