Core i5 3570K processor review -
Meet the Sandy Bridge Architecture
The Ivy Bridge architecture
First up, we'll address the technical overview of the architecture. Chances are good that you already have read, if so please do skip onwards a page or 3-4. Right, where Sandy Bridge really was a completely new architecture, Ivy Bridge di show a lot of common denominators with Sandy Bridge, aside from the IGP. The foremost complicating factor was moving the architecture towards a smaller production node, Ivy Bridge is a 22nm processor series. The processor series has 1.4 Billion transistors and a 160mm2 die size.
Inside the processor die, merged deeply in there, we spot an integrated GPU (I really like to call it a video processor though) based on Intel 4000 series graphics, with roughly twice the performance of the last generation we saw from say a Core i7 2600 processor.
That definitely is an improvement in the low-end segment, excellent news for ultra portables, notebooks and net-PCs. Obviously the AVX instruction set extensions are present in Ivy Bridge as well as an updated Turbo engine (now 2.0) allowing more efficient per core performance and clock and higher Turbo frequencies.
We noticed really good power consumption especially in idle without a dedicated graphics card.
Now you can run an Ivy Bridge processor on a series 6 chipset like Z68 IF your motherboard manufacturer supplies you with an updated BIOS. But should you go all new, Z77 will be the primary and most interesting chipset in a new motherboard. With Z77 you will also gain native USB 3.0 support and PCIe Gen 3 slot compatibility.
What has Intel been releasing in 2012/2013?
Intel released the 3rd generation Core i3/i5/i7 processor family. Though this review is all about the the Core i5 3570K processors, below you can see a small overview for desktop processors:
Desktop Core i7 processors: i7-3770K, i7-3770, 3770T, 3770S
Desktop Core i5 processors: i5-3570K, 3550, 3550S, 3450, 3450S
What's interesting from a naming point of view is that Intel chooses three different suffixes for the processors, we have a K model, a T model and a S model. A little confusing, but it does make some sense:
- The K suffix denotes a processor with its multiplier unlocked
- The S suffix is a SKU with slightly better power consumption and lower clock frequency
- The T suffix is a SKU with low power consumption for optimal energy savings
As quick example the 3770:
- Regular model TDP = 77 Watts (locked)
- K model TDP = 77 Watts (unlocked)
- S model TDP = 65 Watts (locked)
- T model TDP = 45 Watts (locked)
The TDP remains a bit of a discussion, as really Intel will note down the 77W versions as 95W in the packaging. Pretty much the design allows 95W, but 77 Watt or lower is what it'll consume really.
Paired with these processors came new motherboard chipsets, eleven in total of which six are intended for desktop processors, namely the H77, Z75, Z77, B75, Q75 and Q77. For end consumers like you and me the H77 chipset will be less performance targeted and comes with support for monitor connectivity. The Z77 chipset is targeted at performance and enthusiast end users allowing much more tweaking and providing performance features.
We review the Core i5 3570K Ivy bridge processor. Will Ivy Bridge be the processor series everything you expected? Go find out in this extensive review here at Guru3D.
Core i5 2500K and Core i7 2600K review
Today we test and review Sandy Bridge, the Intel Core i7-2600K and Intel Core i5-2500K processors. We will pair the 2600K processor with the Intel Desktop Motherboard DP67BG and also run a test with the Intel Core i5-2500K processor on a Intel DH67BL motherboard
Core i5 655K and Core i7 875K processor review
Intel today releases two new processors targeted at a somewhat more enthusiast audience. Yes, processors for tweakers and overclockers. On socket LGA 1156 Intel now releases two K series processors. The 32nm Intel Core i5-655K processor has the very same specifications as the Core i5 650; it will operate at 3.2 GHz, will feature two cores with Hyper-Threading technology, sport 4MB of L3 cache and will be made using 32nm process technology. The difference between the 650 and 655K is the unlocked multiplier only. Then we have the enthusiast class Intel Core i7-875K processor, it has the very same specifications as the Core i7 870; it will operate at 2.93GHz, will feature four cores with Hyper-Threading technology, sport 8MB of L3 cache and will be made using 45nm process technology. The only difference between the two central processing units (CPUs) will be the unlocked multiplier on the 875K chip, which will allow overclockers and enthusiasts to easily boost clock-speed of the product without the necessity of overclocking other parts of their systems.
Core i5 650 - 660 and 661 processor review
The time has come for Intel to debut a new line of mainstream 32nm processors, which we have all learned to recognize under the codename 'Clarkdale', the new CPUs will be aimed at the mainstream desktop PC segment and will complement the chip maker's Core i3 and Core i5 line of products. The Intel processor lineup will include the Core i3 530 and 540 models, as well as the Core i5 650, 660, 661, and 670, which will be featured with Hyper-Threading, 4MB of L3 cache and support for dual-channel DDR3-1333 memory. Well, that and an integrated GPU as well of course. Guru3D will put the Core i5 650, 660 and 661 to the test.
