The Contenders, episode four (or is it five? I forget)



Author’s note:
I won’t bother with the whole series, just know that I have been considering a replacement for my current computer and this is the survey of possible contenders.
I started off looking at server machines because I like reliable solid gear but after digging into the costs of buying the parts and seeing it was around $10k I decide to rethink. 
Here is the chart I made up comparing CPU power and cost for high end desktop gear:



So, from the CPU chart it can be seen that although server grade Xeon CPUs beat the heck out of anything else, the wallet is going to be bitten hard: and note that cost is only the CPUs, one must add in the cost of the rest of the machine too . . . . . . so why insist on server gear? Will I be running it 24/7? nope. Will it need to be running full bore all the time? Nope.
Ten grand is a year’s worth of savings for me so anything I buy better be worth it.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Sooooo . . . . how about the latest Intel CPUs?
The Core i9-7980XE looks impressive but once again the wallet will suffer for it and then there are a couple of other issues: first, it uses a lot of power and generates a lot of heat to get that performance so you better make sure it has lots of cooling, and then there is the matter of getting hold of one: nobody is selling made up machines with one in . . . . .
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So that leads to the current top-of-the-heap from Intel, the Core i9-7900X.
I wouldn’t be getting one without a GTX 1080 Ti GPU card as that is the best current one - so, after a bit of digging around here are a new group of contenders - all have the 7900X and a GTX1080 Ti, I didn’t care so much about the other bits.

(1) PCCG Phantom                                                         $6899
Has two 1080 Ti’s in SLI (joined config)

(2) Alienware Area 51                                                   $5999 ($1000 discount)

(3) Kenjun Special                                                         $5084

(4) Newegg Battlebox                                                    $4257

This might look simple but there are hidden costs: all must be shipped to your door and the Newegg will come from California. I can’t get any info about how much shipping will cost at the moment – Newegg didn’t answer my question. 

Both (1) and (3) ship inside Australia. If I knew what the shipping cost of the Battlebox was I might choose it first but I get that sneaky feeling it’s going to hike up the price near the $5k line again and the Battlebox has one of those garish glass-n-lights boxes too. 

The PCCG is a bit pricey - even if you pull one of the GTX cards and The SLI bridge out, it still comes in at $5561 - and they won’t let you change the config, you have to take what they sell and change it yourself after which sucks. 

The best is the Kenjun, they will let you change things once you have placed your order and it comes in a plain black case instead of one of those ugly glass-and-lights thingos. They are based in QLD so it should not be too pricey to get a delivery and I could even maybe get the door replaced with one that does not have glass but sound deadening instead. Nice, quiet, plain black box: I want all the action in my computer to be on the screen.
-----------------------------------------------------
This should give a net performance gain of either 164 % according to Passmark or 184% according to Geekbench when compared to my current computer. 
Yeah, benchmarking is crap huh? If you get nothing else from this article, bear this in mind. Look at the three benchmarking columns above - and how consistent they are. not. 
 -----------------------------------------------------
I was really hoping to double my performance but the only way to do that without going overboard is the 7980XE – well, unless I go back to the server gear again and that adds $4k-$5k to the cost.

Considering that this (current) computer has cost me about $7k without including several extras (SSD’s, GPU card, RAM), paying out $5k doesn’t sound too bad. It also has upgrade potential that the old one lacks. Well, okay, it looks that way at the moment but then many have been infuriated in the past by changes in sockets, chips and so on so it doesn’t pay to get too optimistic about that.

Well, regardless of that, I maintain that if it took me six months to save the money I should take a corresponding long time to spend it too.
