A New Chipset for Haswell – 8 Series
With a new architecture comes a new chipset – “8 Series” with the top model being the Z87. Here’s how that breaks down:
A few key improvements have been made over Z77. The total number of USB ports remains 14, but up to 6 can be USB 3.0 now, up from 4 on the 7 series. And yes, all six SATA ports are full speed SATA3 6 Gbps ports now. Finally.
The CPU still only holds up to 16 PCI-E lanes, while the PCH adds 8 more – and those are still only PCI-E 2.0. It’s odd that Intel improved everything but this; I assume the reason has more to do with segmenting the market than anything. Want a full 32 lanes of PCI-E 3.0 going to your video cards? Get an Extreme Edition.
Note that while Haswell uses a new socket format – LGA 1150, heatsinks are 100% compatible with LGA 1155.
The Launch Lineup
Unlike most Intel CPU launches, the number of different quad core desktop SKUs is pretty high – and it’s even bigger on the mobile side. Here’s what is being announced today – there is one Core i5 model that can’t be included on this list just yet.
|Model||Cores Threads||CPU Base||CPU Turbo||TDP||Graphics||L3 Cache||Package||Missing Features||Price|
|Core i7 4770K||4/8||3.5 GHz||3.9 GHz||84W||HD 4600||8MB||LGA 1150||Intel® vPro / TXT / VT-d / Intel® SIPP||$339*|
|Core i7 4770||4/8||3.4 GHz||3.9 GHz||84W||HD 4600||8MB||LGA 1150||$303*|
|Core i7 4770S||4/8||3.1 GHz||3.9 GHz||65W||HD 4600||8MB||LGA 1150||$303*|

|Core i7 4765T||4/8||2.0 GHz||3.0 GHz||35W||HD 4600||8MB||LGA 1150||$303*|
|Core i5 4670K||4/4||3.4 GHz||3.8 GHz||84W||HD 4600||6MB||LGA 1150||Intel® vPro / TXT / VT-d / Intel® SIPP||$242*|
|Core i5 4670||4/4||3.4 GHz||3.8 GHz||84W||HD 4600||6MB||LGA 1150||$213*|
|Core i5 4670S||4/4||3.1 GHz||3.8 GHz||65W||HD 4600||6MB||LGA 1150||$213*|
|Core i5 4670T||4/4||2.3 GHz||3.3 GHz||45W||HD 4600||6MB||LGA 1150||$213*|
|Core i5 4570||4/4||3.2 GHz||3.6 GHz||84W||HD 4600||6MB||LGA 1150||$192*|
|Core i5 4570S||4/4||2.9 GHz||3.6 GHz||65W||HD 4600||6MB||LGA 1150||$192*|
All models support AVX2 instructions, Quick Sync, AES-NI, PCIe 3.0, Intel Virtualization Technology, and DDR3-1600 Memory
On one hand, that looks like a lot of different models. On the other, they all have almost the exact same name. To clear things up a bit:
K = mutliplier unlocked
S = Low Energy Desktop
T = Ultra Low Energy Desktop
R = OEM only – BGA model, must be soldered onto a board
You’ll note that clock speeds are tweaked here and there to manipulate TDP. The lower the wattage, the less of a chance that CPU has of maintaining its turbo frequency. As far as I can tell, the GPU is the same on each, with the same 20 execution units and clock speeds (K series iGPUs can reach 1250 MHz while others reach 1200). The only difference is the R model, something you will only be able to buy as part of an integrated solution. This is the “soldered Core i7” everyone was freaking out about earlier this year.
As for Core i5, it’s the same story as before – everything the Core i7 has, but without Hyperthreading and slightly less L3 cache. This has a negligible effect on performance, making the Core i5 the sweet spot for most gamers and enthusiasts. Unfortunately we don’t have one to review just yet.
Here’s another chart, comparing the two models you’ll care about, up against the rest of Intel’s current lineup of unlocked CPUs:
|Model||Cores Threads||CPU Base||CPU Turbo||TDP||Graphics||L3 Cache||Package||Price2|
|Core i7 3970X||6/12||3.5 GHz||4.0 GHz||150W||15MB||LGA 2011||$1030|
|Core i7 3930K||6/12||3.2 GHz||3.8 GHz||130W||12MB||LGA 2011||$569|
|Core i7 4770K||4/8||3.5 GHz||3.9 GHz||84W||HD 4600||8MB||LGA 1150||$339*|
|Core i7 3770K||4/8||3.5 GHz||3.9 GHz||77W||HD 4000||8MB||LGA 1155||$330|
|Core i5 4670K||4/4||3.4 GHz||3.8 GHz||84W||HD 4600||6MB||LGA 1150||$242*|
|Core i5 3570K||4/4||3.4 GHz||3.8 GHz||77W||HD 4000||6MB||LGA 1155||$230|
As you can see, the Core i7 4770K and Core i5 4670K are almost identical to the Ivy Bridge models they supplant. This will give us a good opportunity to discover the clock-for-clock speed increases Haswell may bring to us.
We keep a pretty narrow scope in most of our CPU reviews, only really considering direct competition usually. This time, we’re going to include some cheaper CPUs to give us an idea of what you get when you increase your budget by certain amounts. We’ll be including an Ivy Bridge Core i7, Core i5, and Core i3, and 3 different CPUs from AMD – FX 8350, FX 6300, and A10 5800K.

As usual, we’ll kick things off with some pure math, courtesy of SiSoftware Sandra 2013. First up are the pure synthetic arithmetic tests, using classic Dhrystone and Whetstone benchmarks:
As far as ‘pure math’ goes, Haswell doesn’t provide anything over Ivy Bridge in terms of clock-for-clock performance. Let’s see what happens when advanced instructions are allowed – including the brand new AVX2 set supported by Haswell:
In the more modern Multimedia tests, Haswell is really able to flex some muscle, giving it a huge boost clock-for-clock over Ivy Bridge. However real world performance is another thing… Something we’ll get to on the next page!
