AMD To Launch Radeon HD4890 "RV790" In April

[purefun65]

I am still skeptical of these supposed tweaks to the core.

So you're essentially buying a 4870 with better power consumption. Wow I hate refreshes.

Who said that? Shintai?

[marten_larsson]

Who said that? Shintai?

Nope, he said it would actually be more power hungry than 4870

Well, it's only two more weeks now..

sorry for delaying photos, i waiting for permission of ASUS

But some new info:

I have complete PDF slides for new graphic cards ... dont ask me for publish anything!

proof:


1. Spec are : 55nm RV790, 800 SP, 850/3900MHz, Power consuption in 2D is better then 4870, in 3D os higher (no internal improvements RBEs, ROPs, SPs)

2. Layout change of PCB is not because more SP or higher Performance, but new Power savings profiles ... card is really cool in 2D

3. You can OC every card to 1 GHz on GPU, and you can to change Voltage too! ! !

my 4870 Toxic is 780/1000 stock, and 24/7 stable @ 860/1200. So I wont gain anything. No radical improvement, its like 8800GTS 512 to 9800 GTX, just power circuitry changes etc, redesign PCB and call it new card, demand 100$ more.

So a 100mhz increase to the core, with a supposed 900-950MHZ oc edition and possible 1000mhz OC is a refresh?

A normal 4870 would not reach these speeds without serious cooling or modding. Also, atleast ATi didn't name this a 5870, and instead named it accordingly.

Oh and.. first post?

[Eastcoasthandle]

hehe, but you can change voltage in CCC! hehehe

Ok, voltage changes within CCC has my attention

[zerazax]

1Ghz on air is nice

1.1 on water?

These in CF with LN2 and we might see some serious power here

[Manicdan]

was 1ghz the max only cause thats the cap in CCC? what could be done using a third party OC tool?

this might be enough of a card to get me to upgrade, but i have to see production reviews first

That's what I'm waiting to hear too, but CCC does stop at 1000 for the base 4890

If RivaTuner can get it up to > 1000 on stock.... that would be some insane performance

Judging by the CCC limits for HD4870 which was 790MHz I would say 1050-1100MHz should be doable on most samples. We all know that most early HD4870 was doing 820-860MHz out of the box with a proper airflow.
I'm looking forward to this card. Personally I might skip it and wait for RV870, but in general it looks like perfect upgrade for someone still ridding older than HD48xx or GF8800 series

welcome to XS!

and yeah ure spot on, unlike 8800GTS>9800GTX>GTS250 this is simply going from 4870>4890, so no renaming

i wonder why they didnt increase mem speeds much though. i thought even the 4870 GDDR5 chips were rated for 1ghz?

[zerazax]

Power savings I think - and maybe because the bandwidth is unused

yeah im basically with you. i have a 2900xt, and it does anything just fine, but not really cool uber graphics at 1920x1200. and i dont think i will go for a 5XXX card since it will be dx11 right? and i dont expect any game to look much better on dx11 until summer of 2011 when i could probably get a 6850ish for under 200$ and be much stronger than a 4890 plus with full dx11. please no one tell me how wrong my statement is with dates or models or prices, im just planning for the future.

850 vs. 4870's 750 improved power usage. This is being said over and over and over. You want me to quote other people instead of him doesn't matter to me.

[ColonelCain]

More proof please...Just b/c it says 800 shaders / 40 Tmus doesn't mean anything.

+1. Please elaborate.

lol it's being said over and over.. by OBR only. Quote those other people, if you can find it (no, FUD sites don't count).

Instead, I'll take this post. and the fact that the die is bigger as facts, rather than some nVidia fanboy who's apparently gaining popularity for showing some random 3dmark results.

Even the very first post of this thread does.

Did Intel101's post just get deleted?

GPUCafe: AMD to Bring 4890 Launch Ahead (Again)?

As far as changes go, I'm going to go ahead and believe what w0mbat said:

The 6% is clk-per-clk and not the overall performance.

Meaning that something had to have changed to get 6% more per clock. Sorry haters, something was changed.

Shhhh, don't you know they like living in their fantasy world where Nvidia completely dominates?

[dinos22]

you guys seen any benchmarks yet?

i've been a bit out of it and what do you know a card just magically shows up on my desk........it's been sitting here gathering dust a bit....maybe i should yank it out and bench a little hey

i havent even heard of these lol >> says Radeon HD 4890 on the box

time to dust off the old computer hey

[ColonelCain]

With all of this talk about the overclocked versions actually being better, I am beginning to worry. It seems that the greatest point of this card is the extremely high overclockability. However, I will be pretty ticked if the "reference" versions are mediocre, and the good cards require the price premium.
