In INC CPU Part 1 we went over a very simplified version of how CPU’s work - in this one we will actually look at available CPUs and determine which one will be the brain of my new PC!
We are going to look at the following attributes for each processor:
1 - Architecture - this essentially provides us with what instructions are available for the processor (Ultimately it is the logical operators available and how they are organized to process the data) - For the sake of this entry we will primarily be looking at the Intel’s Haswell-E architecture, which supports DDR4 RAM.
2 - Clock Speed (Frequency) - the GHz number
3 - Cores - number of processing units
4 - Memory Supported - (EXAMPLE: DDR4 2133) Important when selecting motherboard to support processor
5 - CPU Socket - (EXAMPLE: LGA 2011-v3) Also Important when selecting motherboard to support processor
6 - Cost - Bye Bye Monies….
So Here we go, I’ve included the primary high end intel desktop processors available - Note that there are no AMD processors, because sadly it is more of a budget gamers pick and we want high end! - there is also one ivy bridge processor because of clock speed, but because of price point it is probably not a contender but we will see based on other component costs.
Intel - Core i7-5820K
1: Haswell-E
2: 3.3GHz (Max Turbo - 3.6 GHz)
3: 6 Cores (Supports hyper threading)
4: DDR4-1333/1600/2133
5: LGA 2011-v3
6: Approx - $ 389.99
Other Notable Info: 28 Max # of PCI Express Lanes (Most high end processors support 40 - In a gaming pc with all the additional high end pci-e cards this could be an issue)
Intel - Core i7-5930K
1: Haswell-E
2: 3.5GHz (Max Turbo - 3.7 GHz)
3: 6 Cores (Supports hyper threading)
4: DDR4-1333/1600/2133
5: LGA 2011-v3
6: Approx - $ 583.99
Other Notable Info:
Intel - Core i7-5960X
1: Haswell-E
2: 3.0GHz (Max Turbo - 3.5 GHz)
3: 8 Cores (Supports hyper threading)
4: DDR4-1333/1600/2133
5: LGA 2011-v3
6: Approx - $ 1059.99
Other Notable Info:
Intel - Core i7-4960X
1: IvyBridge-E
2: 3.6GHz (Max Turbo - 4.0 GHz)
3: 6 Cores (Supports hyper threading)
4: DDR3-1333/1600/1866
5: FCLGA2011
6: Approx - $ 1059.99
Other Notable Info:
Luckily - All but the IvyBridge-E processor use the same socket and RAM so when looking at motherboards and RAM we can take that into consideration. Another thing to keep in mind is overclocking the CPU - after doing a bit of research the Core i7-5960X can be overclocked to as high as 4.6 GHz, which makes it a pretty good deal in terms of clock speed AND cores - additionally Newegg and Amazon list the price point at 1049.99 which is better than suggested retail price on Intel site.
In terms of consistency, stability and reliability all reviews read seem to be very similar in that all three Haswell-E processors run pretty hot, especially overclocked, but are nonetheless stable and consistent
In terms of processors - we will start by basing the PC off of the Intel - Core i7-5960X - if cost becomes an issue we may look at the Intel - Core i7-5930K. I think the Intel - Core i7-5820K is a no-go because clock speed is less than the Intel - Core i7-5930K and the number of PCI-e lanes is a little unsettling. The reason being I’m unsure at this point how many lanes are used by the newer high end PCIe cards (Mainly the graphic and network cards).
