AMD’s Radeon HD 5770 & 5750: DirectX 11 for the Mainstream Crowd

BattleForge
BattleForge is EA’s card-based online-only RTS. As the first DirectX11 title it’s of particular importance for the latest rendition of DirectX, although in this case we aren’t using any features that would be impacted by it. Even without ambient occlusion, BattleForge manages to be a rather punishing game for GPUs.
BattleForge is another game that punishes the 5700 series. The performance hit coming from the 4870 starts at 25% at 1680, and ends at just 18% at 2560. This also means that the 5770 loses to the GTX 260.
As for the 5750, it loses at 1680 by 7%, but eeks out a very slight win at 1920. Apparently being memory bandwidth starved isn’t so bad when your competitor is too.
Finally, this gives us one of the larger gaps between the 5770 and 5850. $100 buys you 60%-70% more performance.

The 4870 will only drop in price to clear inventory, because it's not worth it to produce them with the intent of selling them at $120 or less. I expect them to sell out before the price drops much further.Don't fret, though. The 5770 has a 128-bit bus and a fairly small die. It will drop in price soon enough, unless NVidia decides to stop bleeding $$ on its huge GT200 chips on $150 cards and Fermi-based mainstream cards can't get down in price.

well, my favorite retailer (alternate.de) already has the 5750 and 5770 in stock, at 130eur and 160eur respectivelythey also have the 4870-1GB at 115eur, which is MUCH cheaper
in any case, right now, with my usage pattern (24/7 on, but mostly GPU-idle, maybe just one hour a day of GPU stress), the difference in power consumption between the 4870 and the 5770 is at least 50w, which means ((50*24*365)/1000)*0.15eur/KWh = 65.7eur/year
so it pays for the difference in just over 6 months, at the expense of slightly lower performance, with the advantage of less noise
speaking of which, I like my GPUs silent, passive if possible, thankyouverymuch, so I'll wait for vendor-specific designs or after-market coolers; by the time these are out, maybe the 4870 will not eve be available anymore

(sorry, that was 8 months, don't know how I got that 6 the first time)7Enigma - Tuesday, October 13, 2009 - link
Search for and download GPUTool. It's still in beta and has some quirks but for massive idle power drop it cannot be beat (at least for my system, 4870). I simply lowered the 2D core/memory clocks (they have a low/medium/high setting, and ALL need to be the same setting or you get flickering), down to around 250MHz, and this dropped idle power consumption by a crazy amount (40-80w, can't remember exactly). Once the creator of the program releases a newer version I'm hoping some of the fan speed and voltage mod bugs get worked out. Even so, the 2 second click to lower idle speeds is incredibly handy.HTH

I don't know if you've tried using ATI tray tool already, but after scourging around the web trying to figure out way to keep my XFX 4870 1GB from drawing more power than needed(e.g. when just surfing/playing video), I was able to drop the GPU clock to 400 MHz, and memory to 225 MHz. The memory draws much more power than does the GPU, so leaving GPU at 400 doesn't really make that much of a difference, compared to 250.Keep in mind that running said program in Vista is somewhat of a headache, since the driver is not signed by MS, so you need to do the work-around to get it running as startup program so the clocks drop can be initiated by the program.

A year later, the 5770 is *cheaper* than the 4850/4870. I just purchased one for $99 from the egg. It consumes 30% less power at idle and at load than the 48xx cards.I suppose at the $160 price point, it was fine to slam this card. At the current price point, though, it is the BEST price-for-performance and performance-per-watt card out there.
