INTEL® CORE™ I5, INTEL CORE I5 3570K REVIEW

  -  

The new go-to gamer"s chip, but is it a Sandy Bridge upgrade?

This is it. The biggie. The replacement for our favourite CPU of the past year or so. The new quad-core Intel vi xử lý core i5 3570K, one of two new processors from Intel"s new 22nm Ivy Bridge family of CPUs, has plenty khổng lồ prove.

Our old favourite that sets the standard this new cpu will be measured by is the Intel core i5 2500K from the Sandy Bridge generation, the best all round gaming CPU ever và all the chip most people need.

Or maybe that should be the vi xử lý core i5 2550K which was a very minor clockspeed bump over the 2500K. In truth, they"re much of a muchness.


At first glance, you might wonder whether the Intel vi xử lý core i5 3570K is actually a new chip, so similar are the headline specifications lớn its predecessor.


With four cores và no Hyperthreading support, there"s not a lot of extra CPU hardware. The clockspeeds & cache haven"t budged an inch, either. As before, we"re talking 3.4GHz nominal, 3.8GHz Turbo & 6MB of cache.


Dig a little deeper và the differences emerge.

For gamers & performance enthusiasts, the most important upgrade is the shrink from 32nm lớn 22nm process technology & the introduction of Intel"s 3 chiều Tri-gate transistors.

The upshot is what intel is calling a "Tick-plus".

A "Tick" in Intel-speak means a die shrink of an existing processor architecture, where a "Tock" is a new design using the old manufacturing tech.

So, the existing chip core i5 2550K is part of the Sandy Bridge Tock family và the new Intel bộ vi xử lý core i5 3570K is an Ivy Bridge Tick.

Got that?

Anywho, whether the Tick-plus label makes any sense, it"ll be Intel"s own CPUs that the core i5 3570K will have khổng lồ beat.

AMD"s FX Bulldozer chips, such as the AMD FX 8150, simply cannot compete when it comes khổng lồ per bộ vi xử lý core performance and that"s what you need for a great gaming CPU.

Which is what the old 2500k và 2550K were all about and what the Intel chip core i5 3570K will have khổng lồ deliver lớn take over where those two left off.

Vital stats

Old & new

So, the new Intel bộ vi xử lý core i5 3570K is an intriguing set of old & new.

What does it look lượt thích when you lift the bonnet? The CPUs cores themselves are pretty much the same as before, barring a few very minor changes.

It"s the process tech that promises the most. Hãng sản xuất intel reckons the new 22nm 3 chiều Tri-gate transistors are more than just your typical process shrink. They offer much better current control, less leak và improve flow.

In theory, that gives hãng sản xuất intel lots of options.



Firstly, with each vi xử lý core consuming less power và taking less space, it could add more cores.

But it didn"t.

Alternatively, hãng intel could have ramped up the clocks.

But it didn"t.

Finally, the new Intel bộ vi xử lý core i5 3570K could be more power efficient than the old Sandy Bridge 2550K.

Here, finally, we some tangible evidence that the new process delivers as billed.

Where the 2550K is rated at 95W, the core i5 3570K has a 77W TDP. That said, with the bộ vi xử lý core count, clocks và 6MB cache carried over, one thing is clear. If the Intel bộ vi xử lý core i5 3570K is to deliver improved performance, those minor vi xử lý core revisions are going to have to bởi the work.



The processor graphics get the real boost

Shift your attention to lớn the graphics part of the new Ivy Bridge architecture, however, & things look a lot more interesting.

If you care about integrated graphics, that is.

The core i5 3570K gets the full fat HD Graphics 4000 core, so that means 16 execution units where the old 2550K had just 12. Each unit gets an tăng cấp too, with more processing power và an upgrade from DX10 khổng lồ DX11 suppport.

The final change of cảnh báo is the addition of PCI Express 3.0.

As before, the main PCI Express controller is integrated into the vi xử lý core i5 3570K"s die & as before you get 16 lanes to play with regards discrete graphics cards. But with double the bandwidth of PCI Express 2.0, the Intel vi xử lý core i5 3570K và other Ivy Bridge chips make a more robust platform for multi-GPU graphics.
