4860 looks very promising

desktop 40nm 4770 is out! mobility 4860 should be very similar.
here's a crysis bench & review:

here's another one (crysis-not so much):

Im hoping ATI can keep up this pace and not do what Nvidia has been doing since, for almost the past year, they done pretty well IMHO.

 

Ugh. I can appreciate ATI's engineering here, they are making some pretty revolutionary chips (ie. 128-bit on a 40nm process with GDDR4/GDDR5 and it still competes with 256-bit chips!) and it feels like nvidia shoves along some relentlessly renamed chip and foils ATI's hard work. But anyway, it'd be nice to see a mobile chip benching around there too, that in itself is an achievement.

 

I think the people at xbitlabs are retarded. It's because of this quote

Basically they're saying all of the cards they tested can't run crysis warhead even at 1280x1024, but of course they can't, not with 4xAA, who the hell tests a mainstream graphics card with AA ONLY? That's a terrible indicator of how something will perform, by using a graphics setting that almost no one will ever use with that game. It's not just that, but every single test uses 4xAA only.

As always I liked the tomshardware review though, and I think they have a good point on the pricing. Setting the price under $100 would have made it far more attractive for buyers than $109. I'm sure it will get to these prices within the next 2 months, but still.

Here's the card, you can already buy it here in the US, and yes that's the stock cooler, which looks alot different than all of their other coolers.

It all depends on where the clocks on the 4860 are set. They definitely won't be 750/750/800 like the 4770.

 

I dont know why I like Nvidia rather than ATI.

 

The 4890 has started to appear now actually, i think it even popped up in there driver section the other day


Apparently a massive performance boost.

 

Wow, that's a helluva card for cheap on the dollar! The 128 bit memory interface and GDDR5 VRAM will also be more power efficient even with higher clocks and higher bandwidth. All ATi graphics cards, mobile or desktop should have GDDR5

 

Kind of an ugly cooler on there I prefer large slot coolers, but I guess they only add to the cost.

 

clocks will be different for the 4860; it'll have a lower core clock than the 4770, but a higher memory clock.

 

I AM BUYING THE ASUS-K51A officially

 

is there any way to downclock a desktop 4770 and stick it into a notebook?

 

No. The PCB needs to be redesigned to be able to make it fit inside a laptop (plus any clock speed/voltage changes).

 

When it comes to relative clocks the desktop 4770 is to the desktop 4850 as the Mobility 4830 is to the Mobility 4850.

The Mobility 4860 should have better performance compared to it's respective 4850 than the 4770 does.

 

I'm still wondering in what kind of notebooks the Mobility 4830 will show up. It's only 128-bit with GDDR3, and its clocks aren't very impressive, but it has 640 stream processors, an amazing number for what looks on paper to be a mid-range mobile card.

 

I'm really glad ATI is putting in new ground breaking technology into mid-range GPU. It lets the average consumer get a chance to purchase it and experience it instead of waiting 2 years or more for the price to drop to even get a chance to pruchase it. In that sense, I'm planning on getting the 4770 now for my desktop soon. Save the energy!

 

I'd like to say that the Mobility 4830 will steal some business from the Nvidia GT 260M but it'll probably end up more often paired with an AMD processor instead of an Intel. I could see it being used in a half-hearted "gaming rig" like Lenovo's 17" Ideapad or overseas in the Fujitsu Amilo 17-18" X series (with an AMD CPU).

If the heat is low though it could really shine in 15-16" notebooks like the Studio XPS 16, or something like what the Toshiba Qosmio F55 was.

 

according to some reviews, the hd4770 consumes less than 50w under load, the 6 pin external power connector not necessary and can put up 100mhz+ overclocks. and it performs very much like a 4850 at stock.
if the specs of hd4860 is finalised, it's only going to be underclocked by 70mhz compared to the desktop version, this should be very interesting.

 

divide that by 5, it has 128 Nvidia equal shader units, thats pretty good still.

 

Well they are not equal, but it does give you a very rough idea of what to expect. In some cases, this idea is complete bunk considering the new Radeon 4550s with 16 x 5dimensional shader units complete trash the Geforce 9400GT which has 16 SIMD shaders. Kind of amazing too. Check out this benchmark comparison:

ATi 4550 vs Geforce 9400GT

 

hd4550 has 64bit bus vs the 128bit bus in the 9400 gt as well.
