Renoir has 8 cores,so the IGP is more TDP limited than in the Intel chip,as AMD went more CPU heavy. Intel went the other way with more GPU than CPU. So the Intel SOC,can dedicate more of its TDP to the GPU,etc so it will boost much higher. Its kind of telling Intel isn't comparing any of its own 8C mobile CPUs,to Renoir.

That is also assuming TDP/peak power consumption is the same for both.

There is also something else to consider,on the latest Intel 10NM SuperFin process(which is meant to have density improvements),the 4C Intel SOC,is the same die size as an 8C Renoir SOC at around 150MM2. So Intel doesn't really have a cost advantage - AMD can sell Renoir in both thin and light laptops,and also in laptops with a decent dGPU such as mobile RTX2060.

After all the CPU part,is literally the same in the new consoles(8 cores with 8MB of L3 cache).

I am talking about something bigger.. I am betting that Intel will continue this momentum into the 2021 HPG launch.. these are expected to be enthusiast grade discrete graphic cards

Anyways IPC is the only metric that I look at while determining architectural superiority it doesn't matter that it would end up consuming 10 W more.. not that I know about it... things would be clear as more reviews trickle in..but I see this momentum as fairly promising

Edit: Also there's no 8 core Tiger Lake yet, so there's nothing to compare to. Intel's new GPU is exclusively available on Tiger Lake

still not hearing what the AMD competition to a 3080 'will be' (accepting it will come a month or more later) with little over 1 week to go before Nvidia availability :eek:

and that is fine btw I'll keep an eye on RDNA3 if this drags out
 
Im quite excited about whats coming. I wasnt thinking of upgrading my 5700XT anytime soon, but if we do get something that sits between 3070 and the 3080 they will get my money. Im happy to wait till after Christmas anyway unless CP2077 tanks hard which depite being an nvidia title we had the tessellation fix that blighted the 7xx series for W3 so I expect Ill be just fine.

Intel has beaten AMD a few times in IGPs. The L4 cache version of Broadwell,and Skylake already did so. Intel basically dedicated more die area for those special versions than AMD did,and used the L4 cache to make up for lack of bandwidth.

If you look at the die plans you can see what I mean with Ice Lake and Tiger Lake:

Both Tigerlake and Renoir are similarly sized,and you can see how the Tigerlake SOC has more of the die area dedicated to the GPU.So in that sense,it does have a more powerful GPU,but also less constrained by sharing power with the cores too(4 vs 8).

In Renoir the cores take up more die area than the GPU,and in Tigerlake the cores take less area than the GPU.

For instance the previous generation Zen+ based APUs,had 11 Vega CUs,but Renoir cut it down to 8CUs but clocked it higher. Power and TDP do matter in mobile SOCs though - apparently the Vega part of Renoir can hit nearly 2.7GHZ with enough power and cooling:

Those are tests from MSI,but the SOC does seem to be quite TDP limited.

That VR bench I posted would seem to indicate that AMD has something that can beat the 3080. How soon, and how much is another question. If they are still silent by the time I have seen the reviews and I have the opportunity to buy a 3080, I'll just buy the 3080 and enjoy it until the dust settles. When something better comes along, I'll decide if I want to hold or a eat some lost resale and flip it.

I *could* wait if I knew there was something worth waiting for and how long the wait would be. -two variables that are still unknown with a little over a week to go. If AMD have something to say, the clock is ticking.

Twinz you will only be mad when the 6800XT edges the 3080 with more vram and a game bundle ;)

I need a GPU to run an old sim (Project Cars 2) on a new-ish VR headset. (HP Reverb) PC2 maxes out at less than 8gb of vram usage so the 3080 has it covered. It should also cut through AMS 2 with ease and iRacing can almost run on a potato.

Once the 3080 gets me to good visuals and 90fps, I'll have to go looking for other things to do with the card , not go looking for a faster card. (Maybe run some benchmarks over and over)

When I'm not in a driving sim in VR, I'm playing something like FTL on a 34" ultrawide 1080p monitor. My "need" for more GPU power is very niche.

I'll wait for reviews, and if the 3080 can do the job, I'll get it unless I have a specific reason to wait. ("Something big is coming"..."someday" won't cut it.)
