AMD Radeon RDNA2 Navi (RX 6500, 6600, 6700, 6800, 6900 XT)

It's early to say, but looking at TPU's review of the one 6600XT they've put up now, N23 can do higher boost clocks than N22 and N21 despite only going upto to 1.150V while N22 and N21 XTXH flavor do 1.200V.

2.6ghz thats quite impressive. RX6600XT is a nice entry level GPU, giving you 11TF of rdna2 performance. Its close to a 2070s in relative performance, how does it hold up to that one in ray tracing?
 



You know its very bad when the card is universally panned not only in every review, but on the amd subreddit, which is one of the most ... unique fandoms ive ever seen.
 
Techpowerup's numbers for the 6600 XT against the 5700 XT seemed much more favorable at a glance compared to Hardware Unboxed/Techspot (I used Techspot's numbers due to being an article) with some glaring outliers. A quick check with some 3rd reviewers seemed to have numbers more in line with HUB (Guru3D Cyberpunk, Eurogamer Doom Eternal).

Running the numbers for the 8 common games (AC Valhalla, Borderlands 3, Cyberpunk 2077, Doom Eternal, Death Stranding, F1 2020, Shadows of the Tomb Raider, Watch Dogs Legion) the difference was 2.5% faster (HUB) versus 9.2% faster (TPU) at 1080p.

AC Valhalla : 4.9%
Borderlands 3 : -1.4% (the one game in which HUB had a "better" result for)
Cyberpunk : 8.9%
Death Stranding : 0.6%
Doom Eternal : 15.5%
F1 2020 : 12.9%
Shadows of the Tomb Raider : 9.5%
Watch Dog Legion : 2%

If we extend this to 1440p the relative performance had the 6600 XT as faster at TPU, but HUB had the 5700 XT slightly faster on average.

What's also interesting is HUB looked into PCIe 3 vs 4 due the possible bigger implications with being x8 lanes. Doom Eternal was the one outlier that had a very significant drop of 25%, at least with their test it meant performance dropping from 5700 XT level to below that of the 5600 XT. This does beg an interesting question in terms of how much of the transistor and power savings were from dropping from x16 to x8 lanes.
 
The fuss over value for money at MSRP is pretty hilarious, given it's about 4% worse than 3060/3060ti.

OcUK will hit $379 for a short period, and will then be around $425 on 6600 XT :)

OcUK is hitting around $500 on 3060Ti here in UK and less on 3060, 6700 XT we are about the same at $750.

3060 in stock at £650 (only SKU in stock, OcUK is open about how it scalps the price due to stock level):

3060 isn't LHR while 3060Ti is LHR, which inflates the price of 3060, too. 3060Ti in stock at (EDIT: price-drop) £430:

▷ Zotac GeForce RTX 3060Ti Twin Edge LHR 8GB GD… | OcUK (overclockers.co.uk)

6700XT in stock at £640 (plenty of SKUs in stock):

So stock is live, cheapest is £375:

30+ cards in total available.

The cheapest SKU was the £330 Powercolor Fighter (and an ASUS, not sure of model), all of which have gone:

RX 6600XT 1080p gaming for $379 on Aug 11 | Page 20 | Overclockers UK Forums

The Sapphire Pulse model is absolutely going insane, already 100+ pre-sold, the £329 models have sold out, some may have over sold. INSANE!

Looks like plenty of people ignored the techtuber RAGE and got an excellent deal.

EDIT: OK, my final update:

https://www.overclockers.co.uk/forums/posts/35025855/

I think you should be OK, we are still downloading orders, but Asus gave us 30 cards at a discounted rate to hit MSRP and we have like 100 in total, other 70 cards at much higher cost to us, but if we oversell we will just ship out of the higher priced inventory. :)

It sounds like they genuinely did have a few hundred cards to sell.

Here in germany you can get 6600XT quite readily for about 440 Euro. Which is a very good price regarding market circumstances, but overpriced given historical context.

3060 isn't LHR while 3060Ti is LHR, which inflates the price of 3060, too.
Isn't 3060 always LHR? Whereas the others need to carry that designator to help differentiate?
 
BTW - card was working for most apps with 21.7.2. driver before its release.
Hash-Rate just shy of 30 MH/s on ETH.

£375 cards still in stock, seemingly nearly 100 at least currently still available at various price points.

500x 3060Ti sold at £430 today, when OcUK dropped the price:

https://www.overclockers.co.uk/forums/posts/35026118/

The 3060Ti was over 500 in stock, but within ten minutes had sold out. :eek:

Seems like OcUK made a bit of a schoolboy error in pricing there.

You're right, the 3060 I linked is actually LHR, but I've seen discussion of 3060s that are not LHR recently and that seems to have confused me.

100W power consumption at ~30MH/s? That should keep it unattractive for miners.
 
That was bog standard, no undervolt, no clocktuning, but also TGP, not TBP. I'll better add that to the above.
 
You know its very bad when the card is universally panned not only in every review, but on the amd subreddit, which is one of the most ... unique fandoms ive ever seen.
The AMD subreddit hasn't been very nice to AMD since Navi 21 released last year and people haven't been able to get cards at MSRP.

That's not to say the 6600XT's price isn't terrible.
But the 6600XT's price is terrible because all graphics cards' price is terrible nowadays. There's obviously no reason for the 6600XT to cost more than half of a 6800XT. The only reason AMD put the MSRP bar so high on that card is because this way they get a larger share of the scalping that the distributors+retailers are doing to customers, but to be honest that sounds fair-ish to me.

Should the global semiconductor+packaging shortage and mining craze go away (spoiler alert: it won't anytime soon), then AMD could price this card down to $275 and probably still make a profit.


What I honestly don't get is all these reviewers panning the 6600XT for its high price because they're comparing it to imaginary prices of Geforces and fellow Radeons.
The 6600XT at $380 sounds terrible compared to the MSRPs of all the graphics cards released until late 2020, but IMO it's a bit silly to claim "it's only $20 below the 3060 Ti" when virtually no one is getting the 3060 Ti for $399.
When I go to Newegg the only graphics cards in stock that I find close to the $380 price are the RT-less Turing models like the 1650 Super (no DLSS or RT for those, whoops.. thankfully FSR does work). The cheapest Geforce with DLSS and RT that I can find is the 2060 for $600.

I get that these reviewers are (like us consumer) frustrated with the ongoing situation, but I wonder if lashing out at AMD for establishing a MSRP that is closer to real street prices is fair here.
TPU did a pretty good job at making performance-per-dollar ratios for the ongoing real prices for each GPU, and here's what they found:


performance-per-dollar_1920-1080.pngperformance-per-dollar_2560-1440.png


If you are searching for the best bang per buck, you will love this page. We looked each card's current USD price up on Newegg and used that and the relative performance numbers to calculate a performance-per-dollar index. For products no longer available, the last available reasonable price point was considered. For recent releases that are completely out of stock, we looked up a realistic price on eBay (brand-new, buy now, USA). If the tested card is at risk of being sold out and resold at higher prices, we estimate a price based on current market conditions and use it. In this case, the vendor MSRP is also indicated as an additional chart bar.


Even if the 6600XT sells for $600, at 1080p it's still the card with DX12 Ultimate features that has the best performance-per-dollar in the market.
And at least this will be terrible for mining, with a 128bit wide GDDR6 bus.




What's also interesting is HUB looked into PCIe 3 vs 4 due the possible bigger implications with being x8 lanes. Doom Eternal was the one outlier that had a very significant drop of 25%, at least with their test it meant performance dropping from 5700 XT level to below that of the 5600 XT. This does beg an interesting question in terms of how much of the transistor and power savings were from dropping from x16 to x8 lanes.
If the difference is that big, then this is a very important point and owners of pre-Zen2 and pre-Rocket Lake should be aware of it.
But then it's also a big problem for all the Cezanne APUs out there that only have PCI Express 3.0, from the widely recommended 5600/5800H to the newly released 5300G and 5700G, for which the 6600 XT should theoretically be a good fit for.
 
And at least this will be terrible for mining, with a 128bit wide GDDR6 bus.
AMD Radeon RX 6600 XT Could Be The Next Mining King, Insane Cryptocurrency Performance of 32 MH/s at Just 55W Reported (wccftech.com)
It looks like AMD's Radeon RX 6600 XT offers a measly 32 MH/s in Daggerhashimotto but at just 55 Watts. The wattage is the most impressive figure here as the previous GPU that was able to deliver such mining performance at a low wattage was an ultra-tweaked GeForce GTX 1660 Ti that delivers around 28 MH/s at 80W. In terms of mining performance per watt, this puts the Radeon RX 6600 XT miles ahead of any graphics card that has come before and ruled in the mining segment.
 
I was gonna make a wisecrack about how I got a Ryzen 5 1600, mobo, 2x8GB ram, and 8GB RX580 for $420 not that many years back and how bad things are now, but with this new crypto news I think I'll just play sad trombone sounds. :(
 
The power consumption of Navi 23 is seriously impressive.

But I’m just confused as to the choice of coolers on most OEM models. It makes no sense to throw that much copper and aluminium on a GPU which consumes around 160w of power under full load. What about some decent blower designs?

RX 6600 XT would be pretty awesome in SFF/mITX builds, especially with a blower cooler to get the heat out of the system.
