Ivy Bridge Architecture Recap
At IDF Intel disclosed much of Ivy's CPU architecture, but below is a quick summary:
- 4-wide front end with µOp cache from Sandy Bridge
- OoO execution engine from Sandy Bridge
- Data structures previously statically shared between threads can now be dynamically shared (e.g. DSB queue), improves single threaded performance
- FP/integer divider delivers 2x throughput compared to Sandy Bridge
- MOV instructions no longer occupy an execution port, potential for improved ILP when MOVs are present
- Power gated DDR3 interface
- DDR3L support
- Max supported DDR3 frequency is now 2800MHz (up from 2133MHz), memory speed can be moved in 200MHz increments
- Lower system agent voltage options, lower voltages at intermediate turbo frequencies, power aware interrupt routing
- Power efficiency improvements related to 22nm
- Configurable TDP
I've highlighted the three big items from a CPU performance standpoint. Much of the gains you'll see will come from those areas coupled with more aggressive turbo frequencies.
On the GPU, the improvements are more significant. Some of the major changes are below:
- DirectX 11 Support
- More execution units (16 vs 12) for GT2 graphics (Intel HD 4000)
- 2x MADs per clock
- EUs can now co-issue more operations
- GPU specific on-die L3 cache
- Faster QuickSync performance
- Lower power consumption due to 22nm

Except the quality is the same as competing AMD products if not worse because of driver issues, but you lose 20-30% performance in every scenario versus the last gen Llano APU. The facts are in this very review.Articuno - Tuesday, March 6, 2012 - link
Sure sounds like Bulldozer at this point, doesn't it?""It's just a driver issue, AMD/Intel will fix it!"
"It's just the review units sent out, AMD/Intel will have a BIOS update at the official release that improves performance!"
"If you overclock it to hell and back, it can almost sort of maybe compete with Intel/AMD!"
"Oh look, there's a new update out that improves performance! Sure it's only 1% performance, applicable in only certain scenarios, but it's better than nothing!"

Aside from that NOT being what I said at all... you do realize you justified the reasoning in your post, right? They're bribing Intel. That doesn't mean they did nothing wrong, it's a BRIBE. Besides, Intel is just as guilty as Microsoft of OEM threatening and hand-holding in the 90s.Makaveli - Tuesday, March 6, 2012 - link
Who the hell is this Sans2212 troll.Dude please do all of us a favour on this site and STFU.
90% of the people reading this site know more than you.
Take your bad english GTFO.
+1 for ban!

If you Google his handle you'll find out he's been doing this for a while now (and that he's probably Japanese, which would explain the poor English).+2 for ban.

I don't think he's serious....reading come of his comments...nobody with a human brain can reason like that...If he IS serious, opens up the possbility of creating an online zoo exhibit out of him...prod him with an AMD logo and he'll roar, shout, roll and snap :)

Poes law in full swing. The morons are indistinguishable from the people trying to look like them.silverblue - Wednesday, March 7, 2012 - link
Awww I missed it... I usually like reading his rants, especially his obsession with "amd craps". He filled the void SiliconDoc vacated.Jamahl - Tuesday, March 6, 2012 - link
Wake me up when intel does something interesting again.MJG79 - Tuesday, March 6, 2012 - link
2009 - $35B in revenue2010 - $44B (1st $40B year)
2011 - $54B (1st $50B year)
$20B revenue growth in 2 years
You wake me up when there is competition again.
