Considering most Ivy Bridge parts aren't hitting 4.6 at all, I think that's rather unlikely they could get a large enough yield to sell. Maybe another golden sample $2k Xeon.
You think they have a huge amount of frequency headroom? Right now the fastest parts turbo up to 4GHz. With mainstream parts and cooling I think they might be able to set base clocks at 4GHz and turbo up to perhaps 4.6GHz or so. That's about 15%. And with mobile they are TDP constrained already.
TSX and AVX/AVX2 are what I believe nudges to the programmers that it's time to really start focusing on multi-threaded performance.
I have a feeling my 4770k is going to last me a very very very long time. Given Intels performance id expect it be no more than 15% slower than a CPU in 5 years time.
May as well get the K given how long ill be keeping it.
That's my target. If you think about it though, that's only a ~55% increase in OCed performance (compared to a i7 920) over the past 4+ years.5Ghz OC would be awesome for this chip!
TSX sure, but AVX isn't about multithreading, its about widening vectors within a single thread- which is, frankly, a lot more tricky to squeeze performance out of. Ganging together more and more operations to perform simultaneously is a LOT harder to do than to just have multiple independent threads in flight. I kind of wish Intel would do something like what AMD has done- let their vector units do either a single 256 bit op per cycle, or do two 128 bit ops per cycle. It gets even more mental when you go to the Xeon Phi- 512 bit vectors!
I'm hoping for ungodly awesome power consumption with a decent overclock and a large undervolt...

Im forced to upgrade due to a poor i7 950 which wont be stable at any overclock it seems. Far Cry 3 crashed 3 times yesterday on stock settings.
I have a motherboard bug which means i get no wifi signal on startup which goes after a reboot. Sometimes my mouse wont move until i unplug and replug it back in.
This PC is a disaster. Its got to go.
Had a PC like that once. My Q6600 based machine definitely was coughing up blood before the end.
You will be much happier with the new PC
That's true, nevertheless people manage. They switched to SSE2 from MMX/iSSE, GPGPU has been sucessfully applied to many problem domains, and from initial reports Xeon Phi was well-received by at least some HPC programmers.TSX sure, but AVX isn't about multithreading, its about widening vectors within a single thread- which is, frankly, a lot more tricky to squeeze performance out of.

This approach doesn't help if you want to increase performance. Let's look at a hypothetical Haswell which aims for the same vector throughput as the actual Haswell, but has 128-bit execution pipes.I kind of wish Intel would do something like what AMD has done- let their vector units do either a single 256 bit op per cycle, or do two 128 bit ops per cycle.
