Looks as though Novatech wasn't kidding when it "accidentally" announced that stock of AMD's Radeon HD 4890 would be arriving March 24th.

The yet-to-be-announced GPU has been making its way around the internet and has already had its GPU pictured, its specification revealed, its pricing established at around £230 for PowerColor's 1GB model, and its overclocking prowess shown off, too.

Further making a mockery of AMD's upcoming launch plans is notorious Novatech forum administrator, GIBBO. With stock presumably landing in Novatech's offices, he has taken the time to compare benchmarks of a Radeon HD 4870 512MB graphics card with a "can't say what this is" mysterious card - no prizes for guessing its name.

Using a 3.2GHz Intel Core 2 Quad processor, an Abit IP35 Pro motherboard, 3GB of DDR2 memory and Samsung SSD drives, he achieved the following benchmark results:

Graphics card 3DMark 2006 Score 3DMark Vantage Score

Radeon HD 4870 (512MB)
Stock clocked on Windows 7

15550 3DMarks 3DMark Score P9358
  GPU Score 8805
  CPU Score 11531
Radeon HD 4890 (1GB)
Stock clocked on Windows Vista
16098 3DMarks 3DMark Score P10211
  GPU Score 9860
  CPU Score 11433
Radeon HD 4890 (1GB)
Overclocked on Windows Vista
16898 3DMarks 3DMark Score P11413
  GPU Score 11412
  CPU Score 11418
Radeon HD 4890 (1GB)
Overclocked on Windows Vista
CPU overclocked to 3.5GHz
18043 3DMarks 3DMark Score P11737
  GPU Score 11520
  CPU Score 12439

No real surprises, and, as expected, the so-called "mysterious" card is clearly quicker than a 512MB Radeon HD 4870 - and it's packing plenty of overclocking promise, too. In percentage terms, the system featuring the stock-clocked Radeon HD 4890 1GB scores 3.5 per cent higher in terms of 3DMarks than a system equipped with a Radeon HD 4870 512MB.

Looking at GPU performance alone, 3DMark Vantage illustrates that the Radeon HD 4890 1GB performs nearly 12 per cent quicker than the Radeon HD 4870 512MB. Overclock the card, and the performance gap can rise to a whopping 30 per cent.

Given Novatech's expected arrival of a PowerColor card, we'd venture to guess that the benchmarked part could very well be PowerColor's Radeon HD 4890 1GB. We can't, of course, attest to the reliability of the benchmarks, but despite the seemingly endless number of leaks relating to this GPU, rest assured that our official verdict - complete with our full suite of benchmarks - will be published once AMD officially launches the card.

“apparently” he didn't even get slapped wrists for the original “accident”, shouldn't results like this be coming from shady Chinese websites and not a UK retailer? all very confusing, its no wonder others are seething
Is it fair to compare performance of a 4870 on W7 with the 4890 on Vista? Seems a bit incongrous to me. Ah well - I shall look forward to the official tests, the subsequent GTS 275 tests and the inevitable 260 price drop.
Why would anyone buy one of these over a 9800GTX+ that can be had for exacly half the price and scores the same in 3d mark 06 :S

I will pretend you didn't say that…! :surprised:

3dMark is not everything ;)
What I find absolutely hilarious is the fact these marketing tactics were used at the other place for years, table turns and the other place throws a complete fit, superb.
