[VC][TT] - [Rumor] Radeon Rx 300: Bermuda, Fiji, Grenada, Tonga and Trinidad

[S.H.O.D.A.N.]

Although the ~6GB of memory can be shared between CPU/VRAM, it appears that 4GB+ usage has been reported.

Before the current generation, multiplatform titles were hitting 3GB of VRAM on PC when the consoles had what? 512MB?

If you want to use consoles as a benchmark for how much VRAM you need, aim for 24 or something.

Radeon HD 4850, 4870, and 4890 had 800 sp's. I should know, I rocked a 4890 for a very long time.

yes, 4870 had 800 VLIW5 SPs at 750MHz

8800GT had 112 SPs at 1500MHz

you can't really compare by the number of SPs alone, the VLIW5 stuff had lower usage/efficiency most of the time compared to Nvidia (and later GCN).

the 8800GT was not far from ATI cards with 400-640 SPs

I don't disagree, but the current console gen is a little different. They are all x86 and using very similar GPUs and we will soon have DX12 as a common element. The last time around saw very different consoles, with X360 and PS3, also with much older archs vs. current PCs.

the ps3 and 360 in terms of hardware were very different, but nothing like ps2 vs xbox for example... both PS3 and 360 had DX9 PC derived GPUs, and at least 1 PowerPC core that looked almost exactly the same,

but even the current consoles have very different software, so it's not that simple I think, they (XB1/PS4) should have more efficient memory usage than PCs

True.

Even though it may suck, and it's not ideal, but I would rather have my dGPU with extra VRAM to perfform better when the bad ports keep a'coming.

At different resolutions with AA and different texture packs yes. Otherwise nothing came close to 2GB for a straight port let alone 3.

Sorry, i kind of thought i might have been off with my numbers there. It's been a while and i'm getting old.

My future proof plan is to land another 290X at @ 300 bucks and crossfire. With nothing really making me push the SB-E(it's not even OC'ed) i can now spend on video cards what i used to spend on MB's, CPU's, memory, etc. Two 290X's should hold me for my 3.686400K gaming machine for a few years i think.

Still four times the amount consoles worked with.

We should have stopped looking at consoles as a benchmark for PC VRAM requirements years ago. You resolution matters. Your settings matter. The quality of code matters. Console unified memory systems do not.
