Does pixel rate and texel rate of gpu improves graphics quality?

arfiavenger · Mar 13, 2015

For example : r9 270x has doubled pixel and texel rate than gtx 750 ti, so any graphics quality difference between these two while playing same games on same res and with same settings?

Matt Dobe · Mar 13, 2015

Graphics quality is going to be whatever the game can render. You may get slightly nicer looking graphics on a better GPU but can only show what the game is programmed/designed to show.

r9 270x will get more FPS at the same quality and resolution than the GTX 750 Ti but there would be no noticeable quality difference if you are using the same game and quality settings.

Yes if all the other specs are the same (which they're not), the GPU with higher pixel and texel rates will preform better. But you can't pick a GPU based on one of it's specs.

I want to buy a r9 270x. Is it is better than gtx 750 ti as it does not have phsyx and i will play nvidia optimized games more than amd optimized?

Epsilon_0EVP · Mar 13, 2015

The 270X is generally faster. However, if you know you'll be playing Nvidia optimized games, they should be relatively close in power, and the 750 Ti is cheaper. I'd go for the 750 Ti, but be aware that games that don't work better on Nvidia will not perform as well as on the 270X.

The 270x should be a bit faster overall, but it's not a huge difference. The 270x is more equivalent to a 760 than a 750 TI.

Check benchmarks to tell which card is faster because the specs are so complicated that testing is really the only way to compare cards.

I want to play acu, farcry 4, ryse son of rome, battlefield 4,crysis 3 like games on 1600×900 res on high-ultra settings. Also i have i3 4150 cpu for your information.

Matt Dobe · Mar 13, 2015

I would choose the 270x over the GTX 750Ti if you want to play those games. Just my opionion

arfiavenger · Mar 13, 2015

If i overclock r9 270x how much fps increase while playing these games..?

Epsilon_0EVP · Mar 13, 2015

Yeah, I agree with Matt Dobe. Either card is under the minimum specs for AC:U, so you might as well get the one with more raw power. Ryse is not particularly optimized on way or another, that I know of, Crysis likes more GPU power regardless of brand, and BF4 is actually considered to be better on AMD, or at least equal. The only game that does benefit from Nvidia is Far Cry 4, but I doubt it would be a noticeable difference. I'd get the 270X if those are the games you'd play.

Do be aware, though, that even at 900p those cards will struggle playing these games at ultra. These are pretty graphically heavy games, and even high-end systems struggle to run them at higher presets. And since neither card meets the minimum specs for at least one of them, I would not expect high framerates at ultra settings.

I need 30+ fps on these games. On high settings r9 270x can give at least 30 fps or i should tweak settings on medium-high.?

harboym · Mar 13, 2015

You will not be able to run ACU on a 750ti or a 270x, even at it's lowest settings.

arfiavenger · Mar 13, 2015

Why..?

Epsilon_0EVP · Mar 13, 2015

I'll list results without sources as I google them. If you want the sources, let me know.

AC:U -> The R9 280 (more powerful than either card you're choosing) does 25fps average at high settings, 1080p. You'll probably be under 30fps at high settings, then. Both cards should fare similarly here.

Far Cry 4 -> At 1050p, which is a tad lower resolution than 1080p, the 270X does just under 60fps and the 750Ti does just over 40fps, at ultra settings.

Ryse -> At 1080p, max settings with no SSAA, the 270X does 48fps, while the 750 Ti does 23 fps

Battlefield 4 -> At ultra settings 1050p, the 270X does 42fps, and the 750 Ti does around 35 (based on GTX 660 performance)

Crysis 3 -> At very high settings 1080p, the 7870 (the old name for the 270X) does 34 fps. I cannot find good info for the 750 Ti at these settings.

Looks like you'll mostly achieve your 30fps at 900p with a 270X. The 750 Ti will be just shy of that, though, so I'd stick to the 270X.

arfiavenger · Mar 13, 2015

I watched a video on youtube playing acu on r9 270x at 1600x900 on medium settings over 30fps

Epsilon_0EVP · Mar 13, 2015

Possibly at lower settings. These results used high settings at 1080p. With a lower resolution like 900p (which reduces workload by about 30%) and slightly lower settings, you just might get 30fps. This also depends on the CPU, though, since AC:U is known to heavily punish that. I don't know how well the i3 you have will perform in this game, though.

Well thanks for all of your efforts.
