question for linus

[capawesome9870]

you just did a video comparing the Asus Z87 Maximus VI Extreme vs the Gigabyte Z87N-WIFI.  both of these have z87 chipsets in them so i would have guess that they would of performed the same. 

 

My question is:

how does different Chipsets affect performance of the games?

 

testing FX 8350 with the 990FX and the 970 Chipset.  both of these chipsets have different bus bandwidths (5200MT/s and 4800MT/s) and different number of PCIe lanes (x16/x16/x4/x4 and x16/x4). 

 

i do not know the Intel bandwidths to the chipset but how do the Bx5, Hx7, and Zx7 (x being 7 or 8) affect performance.  (i do know that there are boards with the x16/x4 PCIe lanes and other with multiple x16 PCIe Lanes)

 

possibly also do crossfire/sli testing with lower end chipsets that offer x16/x4 PCIe lanes and see how that compares to a better chipset that has x16/x16 PCIe lanes. 

 

 

 

 

Thanks Linus and Slick, i found your youtube Channel because i seen a recommended video (a wan show) that had Logan from Tek syndicate in it, subscribed ever since.  i decided to make  profile on the forums because of the question i posed above.  thanks especially if you answer

 

 

 

ps. i am looking at getting a FX 8350 processor with an ASUS M5A97 R2.0 ($262 with CPU/mobo) or a ASUS M5A99FX PRO R2.0 ($312 with CPU/mobo).  so this question is a little more appropriate for me than how do 2 boards with the same chipset differ.  i am leaning to the 990FX because of a better PCIe lanes and better VRM for the 140w+ FX 8350.

Linus might not see this, if you want to ask directly from him you can just send him a PM

There are already benchmarks regarding pci-e slots and how much they affect gpus.

Basically, stay pci-e 2.0 x16,  pci-e 3.0 x8, or above for each lane and you'll be fine.

Disregard the chipset. There are varying differences. Just check the pci-e slots. A good way to tell if they meet this requirement is if they are 'sli ready' since that basically means they are 3.0 x8 lanes or better.

Chipsets do not really affect game performance.  At this point they are basically just I/O controllers for your USB and SATA.  The GPU and CPU communicate through the PCI Express bus which is a direct path between the two.  The chipsets do have a few secondary PCIe lanes, but those are used for ethernet or other I/O, or the x1 slots on the boards.  They are not used for x16 slots.

The main difference between chipsets in terms of performance these days is whether they are overclocking-enabled days

Whoa, first post and already a question to mr. tech tips himself. Aiming high ^^

Thanks, 

i do not know how the x16/x4 SLI would perform.  all of those test were with x8/x8 and x16/x16 and there was a small performance hit from one to the other.  I would imagine that a x4 in the mix would only affect performance even more than those.

Thanks Linus, 

i was just thinking that the 4800MT/s vs 5200MT/s would have difference performance.  Although very minimal i would think more quantifiable than different boards with the same chipset.  Also i have not been able to find good benchmarks comparing the different chipsets with the same CPU, and figured it would be a good review for a reviewer like your self to do.

Thanks, Twitter gave it wings.
