DirectX12 and the 970?

[foreign]

regarding ram:

 

[Sauron]

Many people say 3,5 gigs just beacuse l

the last 500 just makes everything lag and thats horible

 

Doesn't matter, saying it has 3.5gb is factually wrong. It has 4gb.

 

but you just clearly said it makes it lag ? ive not had any lag? you must believe anything you read on the internet, ignorant is what you are.

 

Lag is not the proper term, it can cause stuttering if you go over 3.5gb (depending on the game and partly on the rest of your configuration).

[Sauron]

Actually, I think an application can either access the 3.5GB pool or the 0.5GB one, but not both.

 

no, games can actually use the second partition if need be, but the card makes sure it's used last.

Oh boy it's this thread again

[Sauron]

Yes its total 4 but its actually 3.5 GDDR5 + 0.5 DDR3+... (4GB of GDDR5 is a lie!)

 

nonono, gddr5 does not indicate a speed. It's all gddr5 memory, but due to how the gpu has been mutilated from the on on the 980 access to the last 0.5gb is bottlenecked compared to the rest and therefore runs at a lower effective speed.

Ye ive heard it those that but that dosent mean everybody is right about it

 

If you're able to post benchmarks showing the "fringe cases" where the slower 500 MB is actually isolated as the cause of a performance problem, please, post them. You'd be the first to do so to my knowledge. You're the one making the claim—prove there's a problem if you believe there is one, it's not everyone else's responsibility to prove there isn't.

 

No tech sites I've seen have actually been able to find cases where the slower memory partition is causing serious performance degradation without resorting to extreme, unrealistic scenarios that would have been unplayable regardless. Nvidia has driver optimizations in place that should be prioritizing the faster 3.5 GB partition for more frequently accessed data. Provided it works properly even most games "using" all 4 GB should still run fine, and there's no evidence to the contrary that I know of.

Maybe but GDDR5 is made to be faster and replace DDR3 is it not? I aint no fancy pancy lawyer but that sounds like its not right to me.

 

I still think it should say 3.5GB GDDR5 + 0.5GB DDR3!  (or slow GDDR5...)

i never had problems with my GTX 970, no stuttering, nothing. And i used 3,8GB Vram already while gaming.

This whole 3,5GB VRAM shitstorm was made by mad poeple, thats the whole story.

The fact that the memory is directly on the card alone is enough to make it much faster than accessing system memory would be. And no, it's not right to say it's ddr3. Would you say underclocked ddr4 is ddr3? It's simply not.

Slow GDDR5 is still a ok name but they should have told everyone...

that's another matter entirely.

Then I've heard wrong...
