Sapphire has a new high-end graphics accelerator in the works for launch next week: the Atomic HD 4890. The card features a blue reference PCB by AMD with a few enhancements, paired with Sapphire's Vapor-X cooler to keep this factory-overclocked card cool, and more importantly, quieter than the reference cooler.

What makes this card even more special is that Sapphire generously overclocked it. The core runs at 1000 MHz, and the 1 GB of GDDR5 memory at 1050 MHz (2100 MHz DDR, 4200 MHz effective). The Catalyst Control Center ATI Overdrive page shows its GPU core overlocking limit upped to 1100 MHz, from the 1000 MHz limit release-drivers were noted to come with. To sustain such high speeds, the card's VRM has been slightly expanded. The card uses an 8-pin PCI-E power connector alongside a 6-pin one. The price of this card is yet to be known.

Some crazy binning is gonna take part at Sapphire, imagine how few will pass the quality control. Won't be a problem for the customers but the quality control is so much more strict. This card will probably have quite hefty price premium, $319 sounds likely but even so it would be a good option, shouldn't have trouble matching GTX 285 at least which is ~$350.

Anyway, nice to see ATI partners finally taking on all the variations of pre oc'd non ref pcb nvidia cards instead of the "boring" default stuff.

With the imminent arrival of the R870 and the G300 this year, I personally could not justify buying one of these cards.

Then again, everyone has a different upgrade cycle I suppose..

i always skip a generation but i got my 4870 b/c my older 8800gtx died.
that goes for cpu too, the next build will be whatever i7's successor in 2010

lesstutrey
04-29-2009, 05:07 PM
with the core at 1000 already, and i know overdrive allows to 1100, this card doesn't really have anywhere to go from what it's running stock... i guess that's not a problem, but i do like overclocking, that's a big part of the fun for me, and cards like this tend to ruin that without voltmods and dice/ln2, and a big chunk of the cost of this thing is the great stock cooling solution.

thx snipeI've seen limits of 1050MHz on some 4890s yet most 4870s will do 1100, the extra 8-Pin PCI-E power connector should help but I was hoping the Toxic would be the first 4890 2GB. However, I was told that a Sapphire rep said that releasing a 2GB at launch would have killed demand for OC 4890s and to expect these around mid May!

I can agree with that. I had a HD3850-256 that I replaced with an 8800GT-256. While the difference is there & noticeable, I'd prefer to wait for significantly-better products until I pop more money on an upgrade. HD5850 perhaps? :p: I hope so!:yepp:

The more I look around the more it appears to be that way.

I bought my HD 4890 right after launch date from ewiz; I really got lucky on it. DOes 980 core / 1175 ram on stock clocks. Max core clock so far was 1050Mhz at 1.45V core.

But theres a lot of HD 4890s that have trouble reaching 950 core even with additional voltage.

thats what i realized when binning memory at cellshock, its a common myth that hardware that clocks well with low voltages clocks well with higher voltages too. there are quite some chips, whether its memory or cpus or gpus, that dont scale with higher voltages... so what you want is high clocks, regardles of voltages...

You forgot to mention temperatures. More often, now that the chips are getting smaller and smaller with higher heat dissipation per area, keeping the whole thing cooler will allow for higher clocks. That's what LN2 cooling is all about... keeping it cold without having to feed it insane voltage, so that it can reach insane clocks.

Note how the new Accelero Xtreme GTX 280 cooler did not help the card overclock any better as shown here: http://www.xbitlabs.com/articles/coolers/display/ac-accelero-xtreme-gtx280_8.html#sect0 Well, Xbitlabs said that " I believe it was the high VRM temperature that wouldn’t let me overclock the card any further with Accelero Xtreme GTX 280 cooler." So, the VRM also gotta be kept cool, if the GPU is going to be overclocked any! 100+ degrees Celsius is just too much. When I took the fans off of my Accelero Xtreme 8800 and used custom fans blowing down from the top, it allowed me to overclock my 8800GTX even better, since VRM was being cooled much better.

Yeah the card is surprisingly fresh, that's a lot of voltage there which the Sapphire card probably won't need. The cooler is very noisy even at 30%, that's the only real let down as it performs nicely.

Not the same card. Overclock a 4890 to 1000 core (and >4000 memory). Performs a bit better than the stock 285GTX.

Bo_Fox
04-30-2009, 05:03 PM
So, I'm guessing it would need at least 1.4v to feed the chip for error-free 1GHz action. Those 8-pin power connectors really support this assumption.

some chips do 1ghz @ stock volts... what makes you think they are not just binning?

madgravity34
05-01-2009, 09:08 AM
They wont "Just" bin these cards as I would assume that 1000ghz @ stock voltages may be harder to come by and thus driving the end price up. This is exactly what sapphire wants to stay away from during these times. They are probably hoping to capture more buyers by offering the highest clocked part at a close to reference unit cost. If I am correct, this will mean they are much more likely to slightly bump core voltage to achieve desired results, stability, and manufacturing numbers.

I love the blue PCB version for the 4890, since all 4890 cards right now are red PCB versions (ugh).. One of my rigs is strictly a purple/green/silver theme, and a blue pcb would look so much better than a red pcb that just does not fit in. It's placed right next to the monitor, with the side off, so the visibility is rather high.

Seriously though, this truly is a triumph worthy of note.

They never said that before.... all they said is that they're using X2 cards to target the high end. This doesn't imply giving up on the high end since NVIDIA can't do the same if they go "massive die" (which implies massive power and cost).

AMDs strategy isn't to make monster chips to compete against Nvidia, they make smaller chips and rely on X2 cards for high-end performance, that is what was said.

So it makes complete sense to me that they are making smaller chips, with less shaders and are advancing in getting higher clocks instead.

Manicdan
05-04-2009, 08:07 AM
i think they should take it anohter step, and make smaller chips, and make X4 cards and allow up to 16x crossfire. i never understood why they can make x2 cards, but only allow 4 chips total, if its just drivers, why not put a bit of work into them and allow people to throw in 3-4 x2 cards and have killer computers.

even with drivers then games have to too etc.. seems like too much of a pain,

what you want is a hardware like X-fire as in like 2 "cores" in one chip if that makes sense and is seen as one :) I think that could be a way to implement it.

I think they use different VRM's instead of the voltera so im thinking not...The card is an AMD reference board `cept the 8pin plug. VRMs are still 3+2 from Volterras so softmod still works.

Then what does it mean when the 8-pin connector is supposedly claimed to allow for 75 more watts?!?The extra 75W is nothing but numbers of spec sheets. Electrically 6pin is identical to 8pin. In real world it has no bearing on how the card is powered, how much there's "available" power, nor on how the card OCs.

05-04-2009, 09:00 AM
I thought the extra grounds connection enables more curent to be allowed through the +12v wires - PSU side of course....

largon
05-04-2009, 09:56 AM
It's not like 6pin plug would be electrically limited in any way.
Infact, a single AWG18 wire common in ATX PSUs can "easily" deliver 8A, at 12V that's 96W.

But ofcourse, the old rule of thumb in everything electric is as follows:

You can never have too many grounds.

Then why not make a card with multiple cores which work in parallel and are recognised by the system as one GPU?

or how it was already suggested... a lot of tiny ones(SP/ALU,Tex, <100mm2) and one master(mem interface, EDRAM,AA, raytracing, display) to rule them all. For mainstream+ segment.

That's kind of what they already do.

A review by AnAndtech.com:

Not the same card. Overclock a 4890 to 1000 core (and >4000 memory). Performs a bit better than the stock 285GTX.

yawn
why not check what volts it's actually running at since it's a factory overclocked model. If they upped the volts then this is nothing special and every 4890 will do those close with slightly upped volts

i dont think that all 4890's will hit 1GHz core with stock volts like some say here
i've got mine on watercooling and it's still doing 980 core 1200 RAM.......i could probably reach a bit more core if i dropped the RAM a bit but this is still benching speed.....................

4890 at 1ghz? they can only hope noone tries furmark or they will get the cards back with blown up VRMs....

Anyway, nice to see ATI partners finally taking on all the variations of pre oc'd non ref pcb nvidia cards instead of the "boring" default stuff.


Im confused, are most of you not able to hit 1GHz? I can run Furmark and play games at 1022MHz, with a max speed (desktop usage only) of 1048MHz... the 4890 was easily my highest OCing card and does it incredibly easy...

Stock volts I can hit about 990, with just .05 increase I am stable to the speeds posted above.

For 1022 core did you have to downclock your memory?
