Intel Ivy Bridge i5-3570K & i7-3770K Review

CPU by leeghoofd @ 2012-04-24

Time seems to fly. Just over one year ago Intel introduced Sandy Bridge to the world. Packing a high performance CPU, with mega overclockability for the K skews, yet keeping power consumption and heat to a bare minimum. The best part was that Sandy Bridge was affordable and even a big threat to Intel's flagship, the socket 1366. World records were smashed at HWBot, as this little socket 1155 CPU overclocked to 5.8Ghz and beyond. The instructions per clock were way faster then anything we were accustomed too. End of last year, it was time to replace the aging socket 1366 by Sandy Bridge-E. The socket 2011 has big potential with it's quad channel RAM support and multi GPU excellence via 40 PCI-E lanes. But the overall clock speeds of the SB-E were disappointing. Most CPU's don't even go over 5500mhz on cold. Today we are gonna introduce the "Die" shrink of the little affordable Sandy Bridge CPU's : Codename Ivy Bridge

Stock Game Tests

When using build in game benchmarks, there's always the big discussion that those tests do NOT reflect real gameplay. Well the objective of the day is to analyze CPU performance, not GPU performance. With a consistent benchmark we are just comparing different outputs. Nothing more nothing less.

Even though we especially see the i5-3570K putting out slightly higher FPS than the i5-2500K, the difference is not going to be noticeable at all. The Ivies seem to be a tad faster, but if we recalculate it in percentages. It's not even going to be worthwhile to talk about.

Another Capcom title is Lost Planet II, supporting DirectX11 graphics. Including two build in benchmarks we opted to run the "A" as it's simulates real game performance. The two Ivy CPU's leading the pack, even if it's only by a very small margin.

It's clear that the Ivy Bridge CPU's are up to the task to finally replace the SB generation. But if you own a SB CPU, it's hardly worthwhile to consider IB as an upgrade. Buying a faster graphics card/SSD will be a better investment.

How about the issues with the heat spreader?
Maybe better to wait on buying one till Intel addresses this issue and switches back to the paste used in SB. If they plan to do that at all?
Other option would be to tear off the heat spreader but I'm not going to risk that on a 300€ CPU

Maybe Intel will correct it but I doub t it as for 24/7 there's no problem,
These CPU's are screamingly fast for daily usage and gaming. For benchers LN2 is the only way to go. Removing IHS for LN2 benching is too risky in my book...

I am waiting to see some retail CPUs benched on air with the HSF removed

Comment from nigel @ 2012/05/01

except for the litle issue with the ihs and such these look just great.

I just hope to see more results with retail samples and modified ihs. Like lapping, no ihs, remounting ihs...

But nonetheless this is my next upgrade

Also nice write up once again
