Intel launched LGA 2011Extreme platform at the end of 2011.
It?s different position as annual renewed LGA 1155 or LGA 1150.
LGA 2011 CPU refresh cycle is longer and having simple product line.
CPU usually has 3 models. Mostly is using X79 chipset.
LGA 2011 launched three Core i7 CPU,Sandy Briidge-E, in the beginning.
After almost 2 years, Ivy Bridge-E was revealed last Sep.
The socket is LGA 2011. Pre-owned X79 users just need to update the BIOS.
Sandy Briidge-E has 3 CPUs.
Entry is Core i7-4820K,3.7~3.9GHz / 4C8T / L3 Cache 10MB.
Mid end is Core i7-4930K,3.4~3.9GHz / 6C12T / L3 Cache 12MB
High end is Core i7-4960X,3.6~4GHz / 6C12T / L3 Cache 15MB
Even 4820is also Ksku. It should be able to adjust multiplier.
4820K is better than former i7-3820 at unlock geature.
Sandy Briidge-E is 22nm and Max TDP is 130W.
LGA 2011 doesn?t build in GPU, so the temperature and heat control should be better.
Below is Intel Core i7-4960X, the dimension is much bigger than LGA 1155.
4960X back side is almost the same as 4930K. Main difference is 4960XL3 Cache is 15MB.
MB is GIGABYTE X79S-UP5-WiFi, the only Intel C606MB so far.
It?s E-ATX, 30.5cm x 26.4cm. Basically normal size ATX Case can support it.
C606 is Server chipset. The CPU support is much better but OC capability will be weaker than X79.
X79S-UP5-WiFi supports 8DIMM DDR3, and max capacity is 64GB.
It supports 2SATA3 and 8SAS devices. It?s good for more HDDs or RAID.
Unless you are using 3 SATA3 SSD, otherwise 8 SAS ports still provide a better expandability.
After all, HDD still cannot break through SATA2 bandwidth.
System Configuration
CPU: Intel Core i7-4960X
MB: GIGABYTE X79S-UP5-WiFi
DRAM: CORSAIR VENGEANCE PRO DDR3 2400 8GX4
VGA: SAPPHIRE Raden HD 6970 CrossFire
SSD: CORSAIR NEUTRON 256GB
POWER: ANTEC High Current Pro 850W
Cooler: Thermalright Archon SB-E X2
OS: Windows8.1 64bit
As i7-4960X test figure will divide into two.
Picture A is default, enable C1E mode.
CPU max clock is 3.6~4.0GHz, and DDR3 1333 CL9 9-9-24 1T.
Picture B is OC, disable C1E mode.
CPU clock is 4.3GHz, and DDR3 2399.6 CL11 13-13-31 2T.
LGA 2011 is the only quad channel supported platform. It?s a great advantage for DDR3 bandwidth.
DDR3 is CORSAIR CMY32GX3M4A2400C11R, Vengeance Pro series.
8GB X 4 support LGA 1155/1150 dual channel and LAG 2011 quad channel.
I will also show you the quad channel and dual channel bandwidth performance.
The clock is DDR3 2400. If it?s LGA 1155Ivy Bridge, the max can be over DDR3 2800.
This LGA 2011 also supports Ivy Bridge-E structure, I think DDR3 2600 is also piossible,
