How much difference does it make if one graphics card has a 300mhz higher clock speed than another graphic card?

flavion3 · Aug 26, 2013

Same as above

lithuan1an · Aug 26, 2013

About what GPU cards are we talking about?

wanderer11 · Aug 26, 2013

As long as they are the same model it won't really matter. They should run fine together at different clock speeds.

lithuan1an · Aug 26, 2013

It doesn't matter? WHAT? When I oc my GPU 100Mhz I get 5-10 more FPS...
I think you are talking about sli/crossfire

mauller07 · Aug 26, 2013

the faster card will clock down to match the speed of the slower clocked card if you are using them in sli or crossfire.

flavion3 · Aug 26, 2013

I'm talking about a GT 620 and GT 210, where the GT 620 has around 300mhz higher clock speed

wanderer11 · Aug 26, 2013

Those cards don't work together. I assumed you were talking about two different cards of the same model. Won't work. End of story.

flavion3 :

Those are two different chipsets. Clock speed is irrelevant.

CommentariesAnd More · Aug 26, 2013

Core Clock Speed - 8-22 FPS
Memory Clock Speed - 0-9 FPS
These are estimates.
How did I bring -
Test Setup -
i5-3570K - 3.8GHZ Turbo
XFX HD 7950 Core Edition -
Core - 800MHz Core V/S 900MHz V/S 1000MHz V/S 1100MHz
Memory - 1000MHz V/S 1100MHz V/S 1200 V/S 1300MHz
Gigabyte GA -B75M-D3H
Primary Drive with games and OS - WD Caviar Blue 500GB WD5000AAKX
Game - Tomb Raider , Inbuilt Benchmark
Ultimate Settings , TressFX ON , Ultra

Dont have exact changes as this test was done when bought Tomb Raider.

EDIT - Was searching for results , and copy/pasted this ,and realised we were talking about GTX 620 and GTX 210.

flavion3 :

it depends , if it's the same graphic card then it makes a big difference(hd 7770 at 700mhz it's slower than 1000 mhz let's say 30~% slower) , if it's a different card then you can't say witch one is faster ex. gtx780 at 700 mhz is mutch faster than hd7770 at 1000mhz (sorry about my english)

flavion3 · Aug 26, 2013

What chipsets are they then? does that mean they can't be compared?

flavion3 · Aug 26, 2013

I just want to know would there be a noticable difference in gaming?

quilciri · Aug 26, 2013

If what you're really trying to ask is what is the performance difference between them, this should help.

http://www.tomshardware.com/reviews/gaming-graphics-card-review,3107-7.html

the 620 will be the faster GPU, but neither one is good for gaming.

kojak53 · Aug 26, 2013

well gt 620 is better than gt 210 , search the benchmarks

flavion3 · Aug 26, 2013

I know the GT 620 is better, but is it a significant performance increase or insignificant?

kojak53 · Aug 26, 2013

620 has a significant performance increse but if you have the money buy a better card for games i find hd 7770 or gtx 650 "good enough" for gaming or at least buy a hd7730

flavion3 · Aug 26, 2013

I would, but my limiting factor is my small form factor 280w power supply, weak and non-upgradeable

quilciri · Aug 26, 2013

Passmark scores the 620 @ 436, and the 210 @ 184. Yes, there will be a noticeable difference, but what games are you trying to play, and what is your budget?

bystander · Aug 26, 2013

flavion3 :

I would not consider it significant enough to buy a new card. Neither card can game worth a damn. Intel's HD 4600 performs better. It is not a gaming card in any way shape or form.

Kari · Aug 26, 2013

i'd say it is pretty darn significant

based on my quick googling it seems gt620 comes in 2 flavors, one is OEM-only and utter crap, the other is retail and somewhat better, the specs match older gt430 pretty much perfectly and it screams of rebranding or at least some less creative solution to fill a certain price bracket.. compare to the hd4550 which is both charts, or 4670 might be even better.... so 3 times faster or there abouts?
it is still pretty slow

edit lol this thread is busy

quilciri · Aug 26, 2013

Your PSU is able to support a 6670 or 7750 (50w and 45w peak TDP respectively). either one of those is vastly superior to the 620 or 210.
the 6670 will run ~$60 new, the 7750 (stronger card) goes for $90.

flavion3 · Aug 26, 2013

I already prematurely bought the 210 card. I bought a HD5450 for my computer, but my bios wouldn't accept it. So i only want to buy nvidia, my computer has a lot of limiting factors, which is why i only want to spend £20 max on a gpu

quilciri · Aug 26, 2013

My sympathies. I assume you can return the card, else you wouldn't have posted in these forums.

In your case I highly recommend grabbing a used card off UK ebay. *much* more card for your money.

this one is much more powerful and still fits under you power requirement.

*p.s. I'm also making the assumption that your PSU does not have a 6 pin connector for video cards. If in fact it does, you can get the even more powerful GTS 250 off UK's ebay for the same price. That card is almost as strong as the 7750, and it's power draw is still low enough for your PSU.
