Honestly, I'm torn on this release. Out of the box, its not much faster than the prior generation, but the power consumption is SUPER low, like almost half in some cases. That is big.
When you unlock it, suddenly you've got multicore performance 20-25% faster, and probably smoother performance due to not hitting power target limits all the time.
I feel like a lot of the negative reviews are really missing the significance of the lower power draw, and how damn good that means the x3D chips this generation could be; as power won't be a limit to clocks/performance in the same way as last generation (especially if they give it a bit more power as those are the gaming/performance orientated chips), there IS higher IPC, and then you'll have the added 3d Vcache benefits.
These also look FANTASTIC for business, or for people who care about performance. Slightly faster performance for 80W vs 150W is kinda crazy efficiency, and if you unlock the power, it draws maybe +5%, but gains around +20-25% multithread. This is genuinely a tweakers playground dependent on use case, it just seems like AMD chose to default to 'ECO' mode out the box this time around.
I'm REALLY looking forward to the 3DVCache parts now...
One of the comments I saw in the GNexus review comments really said a lot to me, a guy running a school lab commented that for them, running 25 machines in one room, with roughly 30-40 degrees lower temperatures and ~80W a machine with only difference being one CPU generation to the next, with no performance loss makes a MASSIVE difference on the AC bills, power consumption, and being able to keep the room at an acceptable noise and thermal/comfort level. Even a home user will benefit from a cooler, quieter computer.
Now imagine this for businesses running hundreds of machines. MASSIVE difference, especially with power being much more expensive in some countries compared to others.
