GeForce GTX 470 PCB and Cooler Pictured, Too

A couple of days after pictures of the PCB and cooling assembly of the GeForce GTX 480 made it to the internet, fresh pictures emerged, this time of the GeForce GTX 470, the slightly toned-down part in the GeForce 400 series. The GTX 470, like the GTX 480, is based on NVIDIA's GF100 core. The reference design PCB is certainly shorter than that of the GTX 480, and compacts its resources. Since the GTX 470 has a 320-bit wide memory interface, it makes do with 10 memory chips, seen surrounding the GPU from three sides. A simpler VRM is used: 4-phase vGPU and 1-phase vMem. Power is drawn in from two 6-pin power connectors.

The fan connects over its usual 4-pin PWM-controlled line. Some smart compacting of components made space for two intakes to be cut out, which help the blower draw in some fresh air. The cooling assembly, again is compacted accordingly. Since these new pictures are more clear, we can see that the area over the GPU isn't devoid of a copper surface as earlier thought. In fact, as some community members observed, it is a base with copper heatpipes making direct contact with the GPU. The cooler has protrusions at the right spots to make contact with memory chips and MOSFETs. The GTX 470 is slated to be the more affordable of the GTX 400 series, which will be unveiled on March 26. Follow the source link for equally good quality photography of the GTX 480's PCB.

Okay they are DHT coolers for certain.


Take back my comments in the 480 thread chaps!

Looks nice...now if we can just get some performance numbers I will be satisfied, and can decide which DX11 card to buy...(the upgrade itch strikes again) :D

If anything, these PCB designs show that a dual-GPU card based on GF100 should be a cakewalk for NVIDIA.

After getting certain other things in check right?

If that's electrical, then things don't look that bad. There are people out there going "ZOMG it will pwn your HVAC in power draw", but the VRM on these boards isn't that elaborate, not even as much as the one on HD 5870 reference. We'll have to wait and see.

I'm pleasantly surprised that this thing looks like it would fit in my case!

Made this for GTX4xx thread, but here too as people might find it interesting.
GTX 470/480 size comparison:

Yep, that GTX 470 PCB looks already like half of GTX 495 PCB. Just rotate second PCB 180 degrees and glue them together, like this :D

Nvidia is making the right choice have different sized cards like that, it will in my opinion save even more money for the GTX 470's hit on price, and will be a card that most people can slap in there rigs without being troubled by 12-14 inch 5970's and 11.5-12 inch 5870s l0l:laugh:

so the dual GPU will be named GTX495 ? Really ? ... Just hope they do as the last single PCB 295.

Very nice looking, now I want it to finally come out and see W1z's review on both cards.

This definitely gives some good hopes for a simple Dual-GPU card based on these.

The two 6-pins hopefully means that nVidia can put together a dual-GPU card with a single 8-pin and a single 6-pin.

From Heise.de -

So erreichte bei vierfachem Antialiasing die GeForce GTX 470 durchschnittlich 29 Bilder pro Sekunde (fps), eine Radeon HD 5870 rund 27 fps, die HD 5850 nur 22 fps. Bei achtfachem Antialiasing allerdings bricht die Leistung der GeForce GTX 470 stark ein. Sie erreicht dann nur noch 20 fps, eine Radeon HD 5870 ist bei knapp 23 fps deutlich schneller, die Radeon HD 5850 (19 fps) unterliegt nur knapp.

Running tesselation on a GTX470 - 470 (29fps), 5870 (27fps), 5850 (22fps).
But switching on AA - 470 (20fps), 5870 (23fps), 5850 (19fps).

Yes, thats the 470, not the more powerful 480 but still, thats a 30% performance drop when AA is enabled (compared to a 13-14% drop in the ATI cards). That poly'whatsitcalled' engine isnt looking so hot now.

Right now i am listening to Judas Priest, so these figures must be real.

The site is reviewing a A2 revision of the G100. The current respin is A3 revision. Also, the GDDR5 seems to be running on ECC. Correct me if I'm wrong though. But ECC is much slower. The new revision probably would perform better and have higher clocks.

AFAIK, ECC is going to be a standard thing on the new GPUs, the HD5800 series runs with ECC also. It doesn't slow down performance a noticeable amount unless there are actually errors.

nVidia willmost likely mirror that PCB like the GTX 295 ;)
I doubt they'll turn the cores 90 degrees at all this time. With 2xNVIO chips missing there will be room to make it more simple way.

No idea what it will be called, I call it just that for ease of recognition. ATI went and ditched x2 and most would have been sure it was 5870x2 instead of 5970.

Single PCB for sure, It'll save money and there isn't really that much stuff to fit in. I'm thinking they could even fit all the memory chips on the front side.

7 on front and back for each core and that NVIO space could fit the rest 3 chips more needed for double GTX 470. But they could stick 5+5 front and back and use the extra space for cheaper but more space taking VRM part.

That. So much speculation going on for months, something real and concrete would be nice. Although seeing the PCBs was nice. These cards can't be that hot with so little stuff. Core maybe, but that isn't hard to cool :)

looks from that photoshop above a GTX495 would literraly be like 14 inches!!! but whatever yanks yer crank!. these look nice and an interesting turn for nvidia. no wonder it took them so long the nvio controller is gone! finally!! less items to cool for watercooling!

Currious question. What is with the white piece of paper covering the back lower plate. I was wondering what kind of connectors this may have. I have a fair idea, but I can't be sure as I can't see that section I hope they are not hiding something small and silly like we care like no initial support for DisplayPort or something.

Considering all the rumors and these picks, someone has to be wrong and I think it is the information about how bad the production issues are. There may be some issues, but it would seem like Nvidia has it well in had now.

It isn't a piece of paper, it is a white box added by some kind of image editting software.

It is done to cover the numbers and labels that could be used to trace the card back to person that leaked the pictures. They probably don't want to loose the privilage of having pre-production cards.

Thuough I think it has already been established that they will have two DVI connectors and a mini-HDMI, at least that is what the GTX480 is supposed to have.

I'm not much a fan of the mini-HDMI idea. Unfortunately that's just one more single-use cable for people to buy, and something that definitely doesn't (and probably won't ever) come with any TV or monitor anywhere. That's HD camcorder equipment! While I don't appreciate the loss of airflow created by ATi's arrangement, I would think two HDMI and one DVI would be more preferable for the type of person looking to purchase this card.

It was just a quick minute edit :laugh: Obviously the components would be more tightly packed and if you but half the memory chips on the back it's even shorter.

Don't really know what was the point of seperate NVIO controller anyways. 8800GT and 9800GTX and rest of the G92 family still gave out picture just fine. Maybe G80 and GT200 was just so big that it was easier to have it seperate? 55nm versions couldn't have it integrated as they were just dieshrinks.

Or seperate NVIO would be better, but they made it integrated to compeate with ATI on price?

And I'm drooling over these just because they would be so easy to cool. They will be way over my budget for a long time, though I have no performance issues either yet :)

I have to agree, especially with DVI to HDMI adaptors. I don't believe there is a need for mini-HDMI, or even regular HDMI on a card, with the exception being lower end HTPC type cards. Though most card manufacturers will probably include a mini-HDMI to HDMI adaptor instead of the current DVI to HDMI adaptors, either way it is an adaptor the manufacturer has to include...

I think you answered your own question. The dies were so big, they had to make the NVIO seperate to improve yields.

The 9800GX2 is a dual PCB card also, and it doesn't have those NVIO chips either.
It is not a matter of being able to "cramp all the stuff in", but it is a matter of "style" lol.

I'm bored now.

Can't we just not all stop with the hype - I think it's giving me cancer.

Let's wait not till the 26th but instead till we have some solid reviews. Every 'new' leak of pictures of a card whose performance is in serious doubt is just another batch of Nvidia PR, whether it's sanctioned or not.

Real world reviews = proper graphics news.
