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

As with all CPU reviews we perform at the Shrimps, we start off with a brief comparison between most of the CPU's that have passed or survived the lab. Always nice to know, if you have some idea of how big the performance gain will be when upgrading. If your CPU is not listed, you can download most of the used tests for free and execute a quick comparative run.

As usual SuperPi 1M kicks it off. With the current gen CPU's, a very short single threaded benchmark. Nevertheless it gives a good idea of IPC ( instructions per clock ). Directly spotting both Ivy Bridge CPU's leading the socket 1155 charts. For the smaller i5-3570K logic, as it runs at 100mhz higher clocks. But even the i7-3770K beats the i7-2700K hands down. The multi-threaded Wprime 32 test clearly shows this new 22nm Tri Gate powered CPU's got a lot going for them.

 

 

And it only get's better. The differences on the longer SuperPi 32M version show the strength of these new CPU's. A 10 second lead is nothing shabby. Overclockers will adore this, as it means, if they can ramp up the speeds high enough, new world records will be set. Even Wprime remains 9 seconds ahead. Job well done Intel !

 

 

 

Even though we have serious gains in Pi, depending massively on bandwith, this does not reflect in the AIDA64 results. Maybe it depends on the beta version we used. The socket 1155 CPU's are all close, very close.

Looking at the Cinebench scores the new Tri Gate CPU's pulling ahead of the quadcore competion. As mentioned in the socket 2011 i7-3820 CPU review we warned about it's short life span. In most of the tests this CPU get's smoked by the socket 1155 ones.

 

 

 

The X264HD test, supporting the AVX instruction, again demonstrates the amasing crunching power these little quadcore CPU's deliver.

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
