Sapphire Radeon HD 4890 ATOMIC: 1,000MHz core - how fast is it?
http://www.hexus.net/content/item.php?item=18359Quote:
We've now seen a steady trickle of partner-designed Radeon HD 4890 graphics cards be unveiled since the launch of the GPU five weeks ago. Radeon HD 4890s ships at either 850MHz core and 3,900MHz memory (XT), or 900MHz core and 3,900MHz (OC) and are available for around £200 for both models.
Sapphire has now unleashed a Radeon HD 4890 that it hopes will steal the thunder from rivals. Encased in a Vapor-X heatsink and pre-overclocked, the ATOMIC version of the card ships with a 1,000MHz core and 4,200MHz memory. The fastest HD 4890 of them all, does it provide good value at £250? We find out.
That's not horrible for a custom cooler + stock OC. Alas £50 is too dear for me.Quote:

if i was buying a 4890, id go with this on, since the cooler looks to be top quality (not sure about noise), and id hope the voltage still has some room left to really see this ramp up past 1100mhz.
PowerColor Liquid Cooled Radeon HD 4890 LCS
http://hothardware.com/Articles/Powe...n-HD-4890-LCs/Quote:
The PC scene is constantly evolving as businesses and individuals make use of next generation products that increase productivity or provide higher levels of entertainment. Bigger, better, faster - these are the insatiable desires of consumers. It doesn't matter if we're speaking of gigahertz or gigabytes, the demand endures and companies do their best to crank out sought after new technology.
As we're currently witnessing, competition for consumer dollars is fierce within respective markets and few can argue that there has never been a better time for those looking to buy. The Radeon HD 4890 is ATI's latest contender and we covered it extensively at launch. Now, overclocked variants of the videocard are rolling out with the goal of squeezing every last bit of performance from the RV790 GPU. Stock heatsinks do well to move the heat from the videocard at reference settings, but overclocking the core and memory quickly surpasses the threshold in which those heatsinks were designed for. That's where PowerColor's HD 4890 LCS liquid cooled videocard comes in. With factory overclocked speeds and increased cooling capability, let's find out what this card has to offer.
They didn't add voltages to the card for extra overclock :stick:Quote:

GeForce GTX 295 Vs. GTX 275 SLI: When Two Are Better Than One
http://www.tomshardware.com/reviews/...-sli,2298.htmlQuote:
he GeForce GTX 275, launched last month, gives us an opportunity to run some interesting thought experiments using Nvidia’s SLI multi-GPU rendering technology.
You see, the graphics processor driving the GTX 275—a 55nm mash-up somewhere between the GeForce GTX 280 and 260—sports the same configuration found in the company’s GeForce GTX 295 (doubled, of course). By putting a pair of GTX 275s up against a GTX 295, we’re essentially able to test one graphics solution operating over the throughput of a single 16-lane PCI Express 2.0 slot against the same arrangement running across two x16 slots.
With all of the core, shader, and memory clocks set to the same frequencies, the only real variable here would seem to be the amount of PCI Express bandwidth available to your SLI setup. In both situations, separate PCBs are attached with Nvidia’s SLI connector. But the story isn’t quite that simple and, as we’ll see in the benchmarks, the performance results don’t always reflect an advantage in one direction or the other.
GeForce GTX 275 Roundup (Gigabyte, EVGA, MSI, Sparkle, BFG)
http://www.hardwarecanucks.com/forum...arkle-bfg.htmlQuote:
The GTX 275 was released a short while ago and while it was in short supply, it can now be found everywhere. With sales of these cards happening on a nearly weekly basis, what better time would there be to do a roundup? Today we look a products from EVGA, BFG, Sparkle, Gigabyte and MSI. A total of SIX GTX 275s passed through the wringer before the dust settled.
Man OTH, you are inhumanly fast...
Well you have rss on the site, anyway at the spec you wrote Mhz instead of MB in most of the memory fields. Otherwise well done.
Sapphire Radeon HD 4890 1GB Atomic Review

:D. That's what I get when I copy / paste. I should know better by now.Quote:

* Nvidia GeForce GTX 275 896MB – operating at 633/1,404/2,268MHz using Forceware 185.68 WHQL
(A bone stock 275 runs at 633/1404/2268)

(A bone stock 285 runs at 648/1467/2448)
The Atomic -vs- bone stock Nvidia
Crysis goes to the 285. (Both high and very high settings)...
Fallout3 goes to the Atomic.
Far Cry 2 goes to the Atomic. (both DX9 and DX10)
Call of Duty goes to the 285.
STALKER goes to the Atomic
GRID goes to the Atomic.
Folding @ Home goes to the 285.
I wish they would have cranked the Core, Shaders, and Memory up some, on the Nvidia cards...
Nvidia might have came out on top more?
What's the OC ceiling of these 1 Gigz HD 4890s ? Using stock cooling and good PSU ?
in the last review it was very limited, but they again, never mention the voltages applied, so i really dont know the answer.
from that review not much difference if any from the standard 4890 to this- vapor-x does the odd fps warrant the price ???Quote:

JH_man
your opinion ive just read review and ok 10% performance increase maybe warrant the price im guna hold out for the big 1 300 series dx11 then we will see crysis wars shine :)
ordered a 4890 tie me over till crimbo
