specifically 1 brand amd
1 product ryzen

4 cores vs 8 cores ?

i'd imagine tdp of 8 cores is about 2x of 4 cores.

this is spcr so tdp and silent cooling is an issue

8 cores though sounds like the future.

the additional cost of 8 cores isn't too much, motherboard and memory is same

more cores means more energy higher utility bills

how much more difficult is it to cool silent 8 cores over 4, balanced against 8 cores offering a better experience

Buy what you need and what fits your budget, really you can do almost anything quiet.

I just finish my TR build with 16 cores, and i can tell you it can be manage totally inaudible at idle, depending on the load it will remain inaudible, its audible under prime95 (still quiet imo for the load) but thats a very unlikely scenario that will happen real world.

But the most important thing is to buy what you need, if you only going to use 2 cores, then buy a dual core, but if you going to use 32 cores then get it. While the prefix of more cores will require more cooling, honestly you can cool it fine, as long as you dont want a very small factor for something that needs a lot of cooling, you will be fine.

Again buy what you need atm, we are entering a CPU war, where both companies are pressuring the other, we will get octa cores at mid end setups now, i expect new cpus every year, to capture market share, AMD is coming with Zen 7nm next year, and Intel is trying to make 10nm work, at the end both architectures are very similar (watch this video), so the era of milking is over.

One last time, buy what you need right now, avoid future proofing, new stuff will come faster now.

the ravenbridge apu is attractive with 4 cores and gpu

i am wondering

will the 7nm die shrink allow for apu to go up to 8 cores since its 2x density
i understand scaling isn't 100% perfect

and then is it better to have 4 cores @ 7nm lower power

or 8 cores @ 7nm and higher power

I've read decent analysis on the next gen APU (Picasso, I believe) by people who analyze the roadmap stuff and leaks and know this stuff way better than I do, and their consensus right now is that it will still be 4 core like Raven Ridge. Perhaps it will be lower power, or higher frequency or whatever, but it looks like it won't increase in cores.

thanks for the heads up,

well if its lower power and higher ipc i'm cool.

still torn between APU or maybe an 8 core 7nm cool running and a fanless GPU

does this mean ps5 and xbox 2 will also be 4 cores even at 7nm?
