OcUK RTX4070 review thread

Any gpu running over 65C from techpowerup's reviews I dont consider to have a good cooler, and the pulse is running at 69.

It runs at that temperature because of the very low acoustics, most that run cards cooler have a more aggressive fan curve, with only the very top end models being capable of running as quiet with lower temperatures. It's more about the fan curve than anything else (as noted in the conclusion).

I dunno, currently running a GTX 2070s and have about £4.5k for a new computer - I'm looking at the RTX 4080, and now the 4070, but I'm very underwhelmed by the price/performance. I have not upgraded my PC in about 5 years, but now looking at the current situation I'm thinking of putting the upgrade off. Everything seems poor in terms of the amount of money you pay and the performance you get. IF I do upgrade, its going to have to be a 13900k / 4090 I think, or its not worth it.

I'm also on a 2070S, but looking to upgrade to a 7800X3D / 7900XTX. Have you considered this?
 
I don't really understand the XT, when you look at the performance figures and difference in MSRP between XT/XTX, it just seems like a card to upsell the XTX.

I also don't understand how anyone can really justify the 4080? It's £200-300 more expensive than the XTX and is more or less the same in rasterised games. It does however smash it in RT, but is that worth the extra £££? I'm not so sure.

I'm fairly sure there isn't £200 of margin in them that AMD can afford to lose

Afford to lose maybe not. But if they cannot make them for £200 cheaper now and still make a profit then that is very sad. Especially when chiplets are meant to have made it cheaper.

I have no facts to back it up, but my feeling is they could drop current prices by £200 and still make a profit. Just won't be 50-60% margin or something like that.
 
I think a cut down Navi 31 with just 4 MCDs would make a better part for the 7800 XT than Navi 32 at this point. Navi 32 specs at this point read like they should belong to a x700 series part. But you know, following Nvidia's lead and all that...

I think both companies are drunk on the lockdown profits. They'll unwind that as slowly as they can. After all what else are we going to buy? ;) They are picking off the rich, impulsive or weak willed right now. Just like a lion stalking the herd :cry:
 
Looking at TPU there is some interesting discrepancies in their own data.

Navi 32 is listed as:

4096 Shaders
4X Mem chiplets (256Bit Bus)

www.techpowerup.com

AMD Navi 32 GPU Specs

3840 Cores, 192 TMUs, 128 ROPs
www.techpowerup.com www.techpowerup.com

And yet for the 7800XT, which is supposed to be the full fat Navi 32 they list it as:

3840 Shaders
192Bit Bus (3X Mem chiplets)

Which is it? I very much doubt the 7800XT only as a 192Bit Bus, also 12GB VRam.

So if any one of them a re true its the first one.

So... the
6800XT: 4608 Shaders at 2250Mhz boost, 16GB/s Memory ICs, 256Bit.
7800XT: 4096 shaders at 2800Mhz boost, 18GB/s Memory ICs, 256Bit.

6800XT has 12% more shaders
7800XT has a 24% higher clock
7800XT has 12% higher memory bandwidth.

The 7800XT is 89% of the 6800XT, add 24% higher clocks = 110% + 12% higher memory bandwidth = 124%

So the 7800XT should be a 15% to 20% faster GPU assuming some scaling loss.

That should put the 7800XT about here....

time to dig out my wafers and costs speculation spreadsheet again.

Die sizes and rough yields are pretty simple. I think I filled this before TPU updated their database with the CU die being 304mm²
www.techpowerup.com

AMD Navi 31 GPU Specs

6144 Cores, 384 TMUs, 192 ROPs
www.techpowerup.com www.techpowerup.com
Anyway, ignoring those few mm², I got something like this:

If we ignore packaging costs, then compared to Navi21 (if wafers were the same price), then Navi31's cost is far closer to Navi22 than Navi21.

Plenty of scope to cut prices as long as they are not packaging constrained.
