XFX HD 7970 vs Palit GeForce GTX670 Jetstream

post #1 of 32
Thread Starter 
Hey guys,

I am looking for a new GPU because i have a new FULL HD screen and my Gigabyte HD6850 doesn't cut it anymore when i try to max out my games.

As the title states, i am not sure which one to go with as for the price its the same down here in AU.

http://www.pccasegear.com/index.php?main_page=product_info&cPath=193_876&products_id=20324

I have 1 screen and i am not sure if i will have the Eyefinity setup i would rather go with something like 27' 1440p later when its more affordable.

Which one should i get? Should i wait for GTX660TI?

Also i will be paring it with 955BE @ 4Ghz (NB 2843)

What are the games you're currently playing?

If you're going to overclock the cards, the 7970 will usually win (as long as you get a decent overclock on it). For the same price, imo the 7970 is a better card. I think the 7970 is a better buy than a 680, and the 670 would be a better buy than a 7970 if you can get it at its RRP ($399).

Since you are suggesting you might go for a 1440p monitor go for a HD 7900 series card . The extra bandwidth proves its worth in demanding games like Metro 2033, Crysis Warhead. You wouldn't want to run into any bottlenecks after spending close to 500 dollars.

XFX Radeon HD 7950 DD Black edition review
http://www.hardocp.com/article/2012/03/01/xfx_radeon_hd_7950_black_edition_video_card_review/7


XFX Radeon HD 7950 DD Black edition (900 Mhz) - $449
http://www.centrecom.com.au/catalog/795a-tdbc-radeon-7950-double-dissipation-black-edition-p-56300.html?sort=3d

Sapphire HD 7950 OC Dual X - $ 459
http://www.centrecom.com.au/catalog/1196-sapphire-radeon-7950-overclock-p-56304.html?sort=3d

Sapphire's Dual X is the best cooling solution. You can keep the card cool at very high overclocks. Getting the HD 7950 OC to 1050 Mhz in AMD CCC is straightforward. For 1080p performance that should be more than enough. When you need the extra performance open up MSI Afterburner (non sapphire HD 7950 card) or Sapphire Trixx (sapphire HD 7950) and get this card to 1150+ Mhz.

A couple of examples to show what happens when GTX 600 cards are bandwidth constrained

Metro 2033

http://www.guru3d.com/article/asus-geforce-gtx-680-asus-directcu-ii-top-review/18

Very high with DOF (AAA) 1080P

HD 7950 (1150 Mhz ) - 50
GTX 670 (1058 / 1137 ) - 39
GTX 680 (1137 core / 1267 Boost) - 41

Crysis Warhead

http://www.anandtech.com/show/5699/nvidia-geforce-gtx-680-review/7

2560 x 1600 Enthusiast 4x AA

XFX HD 7950 (900 Mhz ) - 34.4
HD 7950 (800 Mhz) - 31.1
GTX 680 - 30.8

From the GTX 680 review

"While Crysis was a strong game for the GTX 580, the same cannot be said of the GTX 680. NVIDIA is off to a very poor start here, with the Radeon HD 7970 easily outperforming the GTX 680, and even the 7950 is tied or nearly tied with the GTX 680 depending on the resolution. On the bright side the GTX 680 does manage to outperform the GTX 580, but only by a relatively meager 17%.

Given the large gap in theoretical performance between the GTX 680 and GTX 580, as it turns out we’ve run into one of the few scenarios where the GTX 680 doesn’t improve on the GTX 580: memory bandwidth. In our overclocking results we discovered that a core overclock had almost no impact on Crysis, whereas a memory overclock improved performance by 8%, almost exactly as much as the memory overclock itself. "


There are other demanding games like Alan Wake, Witcher 2, Shogun 2, Anno 2070 where a HD 7950 OC will easily beat a GTX 670 OC.

http://www.hardware.fr/articles/866-9/benchmark-alan-wake.html

I don't know about you but I would consider the performance lead in games like Metro 2033, Crysis Warhead more important because it gives and idea of how the cards perform when al the resources are stressed out - shading power, ROP, bandwidth. In games like Skyrim, Dirt 3 where GTX 670 leads both the cards are comfortably doing 70+ fps at 1600p. Also HD 7950 OC scales perfectly with extra clock. So at 1100+ speeds the gap would be negligible in such less demanding games thumb.gif

I play Crysis,BF2/3,COD,Dirt,NFS,METRO 2033,MAFIA,GTA IV you know all these common games. The reason i am not sure which card to get is because HD7970 is on sale for $499 and GTX670 isn't, i don't really like paying full price for PC parts because they drop dramatically with time. I think i would have to wait another 6 months in order to get GTX670 at $399.

Thanks for such a long post, the information is very helpful indeed, just i always thought that HD7950 was never a good value ,for extra $60 i can get 7970 and overclock it to its max biggrin.gif

I am leaning towards 7970 just i have been on ATI team for a few years now and i just wanted to try something different,i read alot of complaints about ATI drivers but i have never had any problems with them so i must be the lucky one.

Another concern that i have is my CPU, do you guys think it will bottleneck 7970 oced? I thought maybe i should get a 3570k + Asrcock extreme 4 z77 mobo and wait for 8xxx series?

I wouldn't get an XFX or Asus card..for 2 different reasons:
XFX gimps the overclocking/voltage control
Asus has 1/2 the pcb thickness of other cards..and also software-locks OCing at a certain point.
I recommend Sapphire,MSI,EVGA, or Gigabyte for graphics

Thats a bit of a problem then.. Only the XFX is on sale for $499

Can you anyone comment about CPU, will it bottleneck the 7970? Should i go with 7850 and overclock it, i read that they overclock really well?

A Phenom II X4 at 4 Ghz should be fast enough. It will not bottleneck the performance. If you want to go HD 7970 thats your choice. Frankly if you are going to OC with MSI Afterburner HD 7970 and HD 7950 cards are going to hit 1150+ speeds. About OCing you don't need to worry. hardocp was able to voltage OC a XFX HD 7950 DD Black edition card with MSI Afterburner. thumb.gif

I am glad that i can hold on to my CPU for a little bit longer. After doing some more research i found that HD7870 will be able to handle all the new games while maintaining a decent amount of FPS at FULL HD? Is 7970 worth the extra $150?
