HD5750 upgrade to HD7770

brianthesnail · Mar 25, 2014

Hi guys
ive seen a radeon HD7770 for £68 and im considering upgrading to it from my current HD5750 .... how much performance will i see moving from a HD5750(sapphire) to a sapphire HD7770 ?
ive also got a ASUS GTX550ti which i know is also fairly good,however i removed this due to the poor drivers since 314.22 ..allthough i could refit it and use that driver ...
basically i want a card that will run the latest games at reasonable detail at 1920x1080 ( 1366x768 minimum ) and from what ive seen the HD7770 has enough performance to do this
many thanks guys

The 7770 has almost double the texel and pixel fill rates that the 5750 has, so a rough estimation would be that the 7770 is almost twice as fast as the 5750--definitely worth it!

The 550 Ti has higher texel fill rate than the 7770, but the 7770 has higher pixel fill rate so it's probably a wash in terms of performance. I'd slap that 550 Ti back in your system (uninstall all AMD drivers, run Display Driver Uninstaller to catch the remnants) and see how it does since you're basically looking at the same performance as the 7770.

The 7770 beats the 550 Ti in almost every game, but not so much that you should get a 7770 if you already have a 550 Ti...

According to the benchmarks the 7770 performs about 50% better than the 5750.

You're not going to see a HUGE increase in gaming if you move from the 5750 to the 7770: http://gpuboss.com/gpus/Radeon-HD-7770-vs-Radeon-HD-5750 But it may be enough to make 1080p gaming feel smoother.
About the same with the 550 Ti: http://gpuboss.com/gpus/Radeon-HD-5750-vs-GeForce-GTX-550-Ti

What make/model PSU do you have?

And the 7770 outperforms the 550Ti by a little bit.

That's because we all answered at the same time. Your's just showed up first.

There's a pretty big performance increase going from a 5750 to a 7770: http://www.anandtech.com/bench/product/537?vs=536

It's huge in some games, less in others, but always ahead (in gaming at least)

thanks guys .....
ive also seen the HD7790 for £82 and its the 1 x 6pin connector version ... this would obviously hammer the HD7770 however ive checked the memory bandwidth and its significantly lower than the HD6790 .and by quite a bit ....( 136gb/sec compared to 96gb/sec ) .. why did AMD reduce the memory interface to just 128bit from 256bit ?
infact its lower than the GTX550ti,s 98gb/sec .. allthough the core and memory clock speeds are higher and the 1.79 tfllops compute power shows its true power
finally a quick question .. im using a ivybridge core i5 3330 and the HD7770 supports pci-express x16 gen3.0 ... and my motherboard is a gigabyte GA-H61MA-D2V which also supports v3.0 ... would i see any improvement using the v3.0 standard compared to v2.1 which is currently used with the HD5750 ?

Here is Tom's graphic card hierarchy chart you can use to see if upgrading is actually worth the cost:

Since 3 tiers seems to be the gauge for upgrading, the HD 7770 may make a nice difference for you after all.

About the PCI-express... Only high end GPUs can actually utilize the 3.0 and GPUs like the 7770 support it but don't gain any real benefit from it.
