Meet The Ivy Bridge Architecture
Where Sandy Bridge really was a completely new architecture, Ivy Bridge shows 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. Let me get it right out of the way, 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 is Intel releasing?
Intel today releases the next (3rd) generation Core i3/i5/i7 processor family. Though today is all about the Core i7 3770K processors, there will be a huge lineup in the months to come, below you can see a small overview of what you can expect based on this new architecture 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)
And amongst these 3770 models the clock frequencies vary as well, we'll show you that later on in the article. BTW the TDP is a bit of a siscussion, as really Intel will note down the 77W versions as 95W. Pretty much the design allows 95W, but 77 Watt or lower is what it'll consume really.
Paired with these processors come 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 i7 3770K Ivy bridge processors alongside Intel's Z77 motherboard. Will Ivy Bridge be the processor series everything you expected? Go find out in this extensive review here at Guru3D.
Core i7 3820 processor review
We review the Core i7 3820 processor. The chip features four computing cores with Hyper-Threading support working at 3.6GHz (3.9GHz max Turbo), 10MB of Level 3 cache memory, a quad-channel memory controller, and a built-in 40-lane PCI Express 3.0 controller.
Core i7 3960X processor and MSI X79A-GD65 review
Today an article covering the Intel Core i7-3960X (Sandy Bridge-E) and X79 based motherboards. An update to the true high-end six-core processor series aimed at consumers. we test with a final sample X79 motherboard from MSI. This article will also review the MSI X79A-GD65 8D. Next to that the fellas from G.Skill provided a Sandy-Bridge-E quad channel memory kit that blew us of our feet, 16GB G.Skill RipjawsZ series memory that with the flick of a BIOS setting to XMP runs stable at 2133 MHz in quad channel.
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
