| Bofferbrauer2 said: I'm interested to see what Zen2 will do in Laptops and APUs early next year, and how they implement these. Will they keep the chiplet designs or go for a more monolithic design? And how will it fare against the newly announced Ice Lake chips there? |
I have a Ryzen 2700u notebook and whilst the CPU performance is adequate for the price point... It leaves much to be desired on the battery front, the 12nm revision aka. the 3700u was only a marginal improvement.
The GPU side of the equation is a little more interesting, the IGP is bandwidth starved, dual-channel DDR4 2400mhz isn't doing their mobile graphics any favors... But it's also TDP limited, if I hold back clockspeeds for the CPU to 70%, the graphics will clock higher resulting in higher gaming performance... The APU's just don't prioritize what parts of the chips should take priority when it comes to gaming properly.
Plus the 2500u with it's lower CU count without tweaking can offer more gaming performance than the 2700u as well in some gaming situations, due to the same TDP reasons. - They have the same TDP, but because the 2500u has less transistors being pushed thanks to a lower CU count, it can spend more TDP dialing up clockrates instead.
AMD's mobile efforts have always been a little hit and miss, hopefully with Zen 2 in notebooks things improve.
Will AMD take the chiplet approach with APU's in Notebooks with Zen2? Who knows. I won't say "no" to a 6-8 core Zen2 APU in notebooks @15w TDP, that will be a worthy upgrade unlike the 3700u.
If AMD takes a chiplet approach it will be interesting to see if the GPU portion will be it's own separate chiplet... In theory that would give AMD more flexibility to mix and match GPU's. Or if it will be part of the CPU cluster or the I/O die/s.
