Japanese website PC Pop managed to acquire a batch of slides pertaining to the upcoming ATI Radeon HD 4770, complete with the first 40nm desktop chip.
You have to admit: there's something sweet about leaked images, whether they're stills from an upcoming movie or the hardware specs of an upcoming graphics card. In this case, PC Pop scored the latter, acquiring six slides showcasing the upcoming ATI Radeon HD 4770.
According to the provided specs, the Radeon HD 4770 (RV470) will run faster than Nvidia's 9800GT, and one slide even announces its $99 price point, lower than the 9800GT's current price tag ranging from $119 to $139. A head-to-head slide reveals that the Radeon HD 4770 features 40nm processing; the 9800GT uses 65nm and 55nm processing. Additionally, the Radeon HD 4770 provides GDDR5 memory, 960 GLOPs of processing power, 12.0 GFLOPS per watt, and 9.7 GFLOPS per dollar. Nvidia's 9800GT isn't quiet as spectacular, using GDDR3 memory and offering 504 GFLOPs of processing power; users also get 4.8 GFLOPs per watt and 5.1 GFLOPs per dollar. To rub Nvidia's face even more into the dirt, AMD's new card supports DirectX 10.1; the 9800GT supports DirectX 10.
Is there a big difference between DirectX 10 and 10.1? A chart provided by AMD shows an improvement, using the PC game STALKER: Clear Sky as a benchmark. Set at 1920x1200 during the day, the game's DirectX 10.1 patch cranks up the frames per second to almost 40. That's not exactly fluid, however it's slightly better than 36 frames per second supplied by DirectX 10. By turning on the sunshafts, DirectX 10.1 still performs better than DirectX 10 without shafts, cranking out around 38 frames per second; DirectX 10 is only capable of 35 frames per second with sunshafts activated.
Outside the DirectX performance, the ATI Radeon HD 4770 features 826 million transistors; the 4670 uses 514 million and the 4850 uses 956 million. Clocking at 750 MHz, the 4770 also features 640 stream processors, a memory clock of 800 MHz using a 128-bit memory bus, a frame buffer size of 512 MB, and consumes 80 watts of power. While the card clocks at the same speed and uses the same memory bus as the 4670, it offers better performance using GDDR5, however it's still not quite as speedy as the 4850. With a compute performance of 1.0 TFLOPs, the 4850 coughs up a core clock of 625 MHz, but provides 800 stream processors, GDDR3 memory using a 256-bit bus, and a memory clock of 1000 MHz to make up the difference.
Sitting between the 4670 and 4850, the upcoming Radeon HD 4770 doesn't look too shabby, and with a $99 price tag, the card should be quite the hot item when it hits retail shelves soon. To check out all eight slides, click on the 4770 pictured above.
Anything below 20-25 becomes laggy and unplayable.
I'm sure you won't even notice the extra fps, but as a former ati fan, I can be happy to know it still holds the crown!
Also have to wonder how hot and loud it runs since it advertises more performance per watt and is on a smaller process while still having a double slot cooling mech.
Either way filling in brackets and increasing competitive pressure is usually a win for us consumers.
i think ati is learning naming schemes from nvidia =[
From what I hear they're retiring the 4830 and at least they went backwards on the numbering... shouldn't be many confused souls out there trying to upgrade from a 4830 to a 4770 (which may or may not be an upgrade) I'd rather this than they rebadge a 3870 as a 4820 or whatever (That'd be closer to what nvidia has been doing)
2. does anyone really care about DX10.0 with DX 11 around the corner?
1. yes, its supposed to be linear, but with a lesser power requirement i think
2. i don't think dx11 will catch on as fast as people think...maybe one or two games to set the bar, but it really has to be something to overtake dx9, which dx10 cudn't do
I'd like to see some XFire benchies of this little puppy.
Esop!
Moving to 40nm process would mean a reduction in price of current gen cards in a month or two after its release, which is good for me coz I am thinking of buying 4870 or 260. Let's see what happens.
DX11-> I don't think it would catch on before a few years. So, 4870 or 260 FTW..
I knew enough about computers to know it would work, and it did; and it made Sims 2 playable at reasonable framerates, though it still skipped here and there. Heck, it even played UT2004 at good framerates.
On a 1024x768 15" LCD monitor that came with the computer. Back then, I didn't know sites like this even existed.
It still serves EVE Online playing purposes to this day at playable framerates (read: 10fps average, OK for a MMORPG where twitch-gameplay is not necessary and with my less-than-stellar reflexes wouldn't have made a difference anyway, except visually) until I graduate from high school and have time to get a part-time job to buy something a little more recent. This card sounds to be a good idea for that project.
...old people :\
anything below 60fps becomes laggy. although playable, it hurts ur ability to play the game. ur fps should be higher than ur monitor's refresh rate to keep the smooth feel as a minimum requirement. just like vsync should be off. all of these factors change ur aim while playing.
granted, i'm in the minority as a high level fps gamer....
