From a marketing perspective wouldn't it be better for AMD to pitch the 1600X as it's answer to the 7700K?
A 6C 12T 1600X for £250 would look & sound a lot better to a potential buyer than a 4C 4T 7700K for £330.
Okay, the 1600X will still lose in single threading performance but those 50% extra cores and threads will still ensure better performance in most multi threaded apps and games or where the 7700K's slightly better IPC & much higher clock speeds will at best only match the 1600X in such tasks.
I've always seen these 6 core parts as the proper rival to the 7700K, not the 1700, as AMD seem to pitch.
From a commercial point of view it would be better for AMD if the 6 core chips could be 4+2, 3+3 or 2+4 parts as it would enable them to use more of the ones that didn't make the 8 core grade during manufacture.
However, because of infinity fabric connecting the CCX's being a bit of a bottleneck I can't see them being able to do so cause the 4+2 chips would perform differently to the 3+3 chips under heavy loads.
I think the 6-core on will tempt me. I'd like more cores than my current i7 4790K but without losing too much in the way of clockspeed for older applications. I don't currently do enough multi-threaded tasks for R7 to be worth the extra.
With regards to marketing, wouldn't it have made far more sense for AMD to go down this route:
R4=4 core (and it's bigger than i3)
R6=6 core (and it's bigger than i5)
R8=8 core (and it's bigger than i7)
Did they want to avoid the unlucky number 4 in China that much?
What have I missed with the most expensive CPU not including a stock cooler?
The 1600X has nearly 50% more heat to dissipate, little point charging the consumer for an inadequate cooler. Having said that my I5 2500K (also 95W) came with a cooler although it only proved useful as a paperweight (and a great way to test the buzzer on my PC when running multi-threaded applications).
While you are here you might as well check out the AMD Ryzen 5 Desktop Processor Sneak Peek video:

A 6 core 12 thread processor at 65 watts is good! Seriously tempted to make a nice build this summer now once it's all settled down. ;)
AT thinks that the R5 1500X has 16MB of cache and the R5 1400 has 8MB of cache:

So it seems the R5 will be a dual CCX design.Quote:
We have confirmation from AMD that there are no silly games going to be played with Ryzen 5. The six-core parts will be a strict 3+3 combination, while the four-core parts will use 2+2. This will be true across all CPUs, ensuring a consistent performance throughout.
Wrong thread.
Does that even make sense? I thought it would be cheaper manufacturing wise to make a dedicated 4 core 1 CCX part.
I had just assumed when they said that the design was scale-able that you could have 1 CCX parts but maybe the design means you have to have at least 2!?
Its a real big shame that the fastest 4 core part turbos to 3.7GHz....I know that's pretty much what we were expecting but was hoping for more...
huh, no R3 at all? Either yields are terrible or AMD is scraping the bottom of the barrel and can't afford another set of masks for a single CCX, a chip with half the cores gated off is very unusual
The 1500X is an oddball - it's got a 200MHz XFR boost, given how low the power consumption is for the 8-core chips I'd expect it to act like a 3.9GHz CPU in practice
