R9 270X Versus RX 570 8GB. Question

[_Murf_]

Playing at 1080P. CPU: AMD FX-8350 (8 core/4.0GHz), 620w PSU, 16GB DDR3 RAM.

Current GPU: Sapphire Radeon R9 270X Battlefield 4 Ed. Video Card - 2GB GDDR5, PCI-Express 3.0 (x16), (factory Overclocked)

Looking at getting a Sapphire Nitro+ RX 570 - 8GB.

I'm currently playing Titanfall2. It has a recommended card of RX480 - 8GB. At times if there is a lot of action going on near me the game will freeze. My card is 3 years old and so I started to look for a new card. I decided on the Sapphire Nitro+ RX 570 - 8GB. (That fits my budget)
Also looking to play Star Wars Battlefront 2 when it comes out later this year.

I tried to look at some of those websites that automatically compare the 2 cards and I can see the numbers in the specs are larger for the RX 570, but I don't know how much larger they need to be for there to be noticeable difference in game play.

My question - I should see a noticeable difference in this card upgrade (at 1080p), correct?
Now the game has to be turned down in settings partly due to the 2GB of VRAM. With this new card, I should be able to turn up the graphics more and have smoother game play shouldn't I?

Thanks for your advice,

You will see a huge difference. The 570's higher clock speeds + Gigs of VRAM will help you a lot.
As for a difference, you will obviously have higher fps but you will probably not get the freezing issue, unless thats due to something else.

It will be a nice jump, but i wouldn't bother with a 8GB version, if you're paying more than a 4GB version it's not really worth it.

Take a 4gb 580 over a 8gb 570 mate.
They're around the same price - some 4gb 580s are actually cheaper.
Its just plain a stronger card.
4gb is fine for 1080p , I'm crushing titanfall 2 with a near 3 year old gtx 970

Thanks everyone for the advice!

The reason I am worried about not getting 8GB, is what if a game in the next 3 years requires 8GB?

That is what I am running into now with Titanfall 2. The video settings limit me because I only have 2GB of VRAM. The recommend specs. for TF2 is 8GB of VRAM.

So I'd rather take the slower 570 with 8GB of VRAM than a 580 with only 4GB of VRAM. Also, I believe the 8GB VRAM is faster RAM than the 4GB VRAM - which I would think slow down the 580 some.

Opinions?

Thanks

WOWOWOWOOW.Is that titanfall 2 or team fortress 2?

EDIT:How stupid was i to not realise that tf2 requires a 2000's pc to run

You're never going to see a game at 1080p that won't be playable on a 4gb card mate .

Honestly If a 8gb 570 & a 4gb 580 are the same price where you are you'd be foolish not to go for the 580..

Ram on the 4gb 580 is same speed as the ram on an 8gb 570.
The base clock is 10% higher on the 580
The 580 has 10% more compute & shader units.

Half the vram or not the 580 offers 10-15% stronger performance in pretty much any title.
It doesn't sound a lot but it may be 2 years down the line.

You really don't need 8GB of VRAM to run Titanfall 2.
A 4GB RX 570 can easily get over 60fps with an 8350.

The rx 570 8gb and rx 580 4gb are the same price.
Boost clock speed:. 570 = 1340 mhz , 580 = 1411 mhz.
They also make a "pulse" version of 580 8gb that boost clock is 1366 mhz and is $10 more.

Sorry to keep beating this, but going from 2gb to 4gb doesn't seem like that big of increase. I am worried that some game will come along that I cannot run at 1080p because I don't have enough ram.
Is that possible, or would I just have to scale back the details or what?

Thanks

You will be fine with 4GB. If you think about it, your getting double the power (obviously its not 2x faster than the 270x but it can make it seem like more of an increase)
There won't be a game released for a while that will require 8gb of VRAM.

 

[amdrx480]

The games that need more than 4gb are less and about 1 or 2 games are released a year. So Rx 580 4gb is going to give you more fps in demanding games.
Also more vram only matter at 1440p+ that your Rx 570 can't handle.

Titanfall 2 came out before the 570 and 580, however you can still use the TF2 benchmarks on 470/480 to judge relative differences. The benchmarks between a 4gb 470 and a 8gb 480 at 1080p high settings show no practical difference. If both cards are over 80fps average, what difference does 4 or 5fps extra make? Enough to justify the extra cost? Not in my opinion.

In 3 years yes maybe that 8gb vram will come in handy, but ask yourself this: If your 270X had 8gb of vram do you think it'd perform like a 570 in today's games? No it would not. The amount of memory is only part of the equation.

This site shows the memory clock at 7000 MHz for the 4gb model and 8000 MHz for the 8gb model.
Why is that?

Who knows ??
The vram on the 470s (both the 4 & 8gb)is the lower speed too.

I'd imagine the slower vram goes in the cheaper cards simply because the 580 8gb is the flagship , you pay more so there are no corners cut.

Don't think for a minute that the ram chips are produced to run at these lower speeds.
They're batched & binned (tested) the ram that will run at higher speeds ends up in the higher tier card, the ram that won't hit that higher speed 100% stabile ends up in in the cheaper cards.

Either way it makes 4-5fps difference max +normally less)

Whichever way you look at it the 580 is stronger on an actual hardware level which is why I'd buynit over a 8gb 570.

The 3 things that affect vram are resolution , Anti aliasing, texture size .

You can always reduce AA, textures ? At 1080p you'll never see the difference between high & ultra texture packs in the games that support them (1440p /4k you would but an RX card isn't strong enough for those resolutions anyway).

Gtv 5 can hit 6gb vram fairly easily if you push settings very high , it'll play on a 4gb card still but pretty much like crap though .
Not because of the vram either , simply because upping the settings that high is behind the capabilities of a mid range card actual performance wise

Thanks everyone for your help.

I ended up getting the Sapphire Radeon NITRO+ RX 580 4GB for $229 at NewEgg. Thought that was a decent price. It was $259 at Amazon.

So hopefully it will last me another 3 years like my current Sapphire card (which still runs, just wanted an upgrade).

Thanks again.

 

[madmatt30]

You'll be happy mate , the nitro 580 is a blazing fast card

 

[GamingEnthusiast420]

$229 is a bargain for such a fast card. Good luck
