2GB GDDR5 vs 4GB GDDR3?

[Seton_]

On my desktop i used to have an R7 260x, 2 gb gddr5 and it easily out-performs the desktop r9 270x in my laptop with 4gb of gddr3. is there a reason? only difference aside from the vram is that the 260 has 28mhz higher clock speed.

 

[atljsf]

faster ram is better than lots of slow ram, especially with games

less ram means that you can't use ultra settings on all games because texture loading proces requires more than 2 gbs sometimes

you can use both, but the ddr5 one will be faster

thanks. also, i love the game watchdogs 2, going on spring break and dont wanna bring my desktop, u the laptop could handle it, even on lower settings?

i7 5500U, 8gb ram, 1920x1080 (im ok with slightly lower resolution too), etc

A desktop R9 270x in a laptop?

Do you mean a r9 M270x? If so:
http://www.game-debate.com/gpu/index.php?gid=2222&gid2=1865&compare=AMD%20Radeon%20R9%20M270X-vs-AMD%20Radeon%20R7%20260X

The laptop variant is much weaker than the desktop variant of that GPU, and as shown, loses by a longshot when put up against the desktop r7 260x. This is not a RAM speed issue.

no looking in the steam system information page, it shows R9 270X, i would imagine that it would show the "M"

what do you think about watchdogs?

 

[atljsf]

watchdogs depends more on the cpu than on the gpu, that cpu is a 2 slow cores and 4 threads, a 5500u is low voltage meant for long battery duration, not fast cpu operation on games

not ideal for this game, expect low framerates

In your laptop? These are pretty large graphics cards. Example:
https://www.newegg.com/Product/Product.aspx?Item=9SIA7HN5HX2819&cm_re=r9_270x-_-9SIA7HN5HX2819-_-Product

What laptop model do you have that can accommodate that size of a GPU? Or do you have an external adapter you plug one of these into that goes into your laptop?

If you're talking about a built in graphics card in your laptop, and not an eGPU or something, then no, it is not a desktop R9 270X. Try using GPU-Z or something to see what it is. And even if it was, the R9 270X uses GDDR5, not GDDR3. In fact, I don't think any GPU produced in years used GDDR3. They either use GDDR5, or regular DDR3 for low end GPUs.

 

[atljsf]

last year and some this year cheap models have discrete gpus with gddr3

if the pc is a amd apu, it has ddr3 for the gpu and for the system

 

[TJ Hooker]

Which one(s)? Most recent cards I can find with GDDR3 are from the Radeon HD 7000 series, and came out 5 years ago.

 

[atljsf]

laptop gpus are we talking about?

desktops, well, you can still buy gt 730 ddr and iirc gt740, r7 250 ddr3, still being produced and sold, there is more at ddr3

on laptops, there is some nvidia quadro for laptops at ddr3, some other models i can't remember atm, surely you will search for them and share them with us, right?

 

[TJ Hooker]

Yes, I specifically said they still make low end GPUs with DDR3. GDDR3 (which is what the OP says his R9 270X uses) hasn't been in use for years as far as I can tell.

What TJ Hooker and I are trying to get across is that the OP does not have the DESKTOP (He specifically wrote desktop) R9 270x in his LAPTOP. Name me a laptop that came out with a discrete r9 270x. "Surely you will search for them and share them with us, right?"

The answer is you can't. The only way it's going to happen is if you use an external GPU adapter. If he's using an adapter: they suck. There's the problem. If he's using the R9 M270x as we suspect, that also isn't as good as the r7 260x desktop graphics card.

With the OP's best interest at heart (and future site visitors with the same question), I cannot let you lead him on to believe that the reason his laptop's GPU is worse is because it's DDR3 RAM. It just isn't true. "laptop gpus are we talking about?" The OP's post stated the R9 270x was "in my laptop". So yes, we're talking about laptop GPUs (not being desktop GPUs, more specifically).

^+1
The reason I'm making a point about the VRAM is that the OP incorrectly said his card used GDDR3 (I've explained why this is almost certainly not the case), which is another indication that he's either misinformed about the details of the graphics card he's dealing with, or misreporting them in this thread.

thank you for taking the time trying to explain to me what the ope said, but i already got it and only replied to the availability of parts around the world, some parts do get lower models like a ddr3 counterpart while north america gets the same but ddr5

since the op hasn't stated clearly what he has and what he wants to connect and do with it since you asked if iti was a external gpu connected via pci express or thunderbolt, well, we can talk and learn, right?

Are you aware that G DDR3 and DDR3 are two different things? Because you seem to think they're interchangeable based on your posts thus far.

 

[atljsf]

never said it was, i mentioned ddr3 as in apus using ddr3 for the gpu, gddr3 is for dedicated gpus on a strict budget

this year i found on sale a laptop with a nvidia 920m ddr3 and also found a ddr5 model, but not avaialble where i live

it seems that you will keep complaining about what i write, at least that is what you have made so far and in the process the op will not get a response or won't come back, that doesn't help

Adding to this, https://en.wikipedia.org/wiki/AMD_Radeon_Rx_200_series
The R9 270x was never manufactured for any memory standard other than GDDR5.

Lets get a few things straight here because this thread is going down the toilet and it needs to be stopped because someone is going to be misinformed.

1. The OP's Problem is NOT the memory (I'll get to that later) but that he is comparing a Laptop GPU to a Desktop GPU, he does not have a Desktop GPU in his Laptop, and the R9 M270X is nowhere near the performance of the desktop R9 270X, this is a common issue with Laptop GPUs that share similar names to desktop ones, and happens on the Nvidia side as well.

2. His R9 M270X does NOT use GDDR3 and in fact GDDR3 hasn't been used since the mid 2000's. The R9 M270X used GDDR5 memory just like the desktop version.

3. While there are some GPUs still available that use DDR3 (NOT GDDR3), they are all 3-4 generations old, they're cheap because they are old. Theres no "current" generation or even last generation models with DDR3. On the laptop side some 2 generation old laptops use DDR3 memory, but again, in this case, not his.

4. AMD APUs do use DDR3, because they use system ram as their VRAM, totally irrelevant to this conversation anyway.

I'm going to change the answer to this thread as its not correct and then close it. There is nothing beneficial to anyone with this fighting. If anyone has an issue private message me. Seton if you have any more questions let me know or feel free to start a new thread.
