ARC A770 and ARC A750:
If you are a regular visitor to our site, you will have seen the first photos of the Intel press kit we received last Friday, which contained the two ARC A770 and ARC A750 graphics cards.
Architecture:
Our two ARC A770 and ARC A750 graphics cards are equipped with the ARC Alchemist architecture. This is the first generation of GPU launched by Intel. The goal of the brand is to continue to offer other cards in the future but it is currently difficult to know at what rate.
The ARC A770 Limited Edition card benefits from an ACM-G10 graphics chip with a 6nm manufacturing process by TSMC. The chip hosts 32 Xe Cores, 32 Ray Tracing units and 512 XMX Engines. It has 16 GB of GDDR6 in 256-bit, which translates into a bandwidth of 560 GB/s. Note that an 8 GB version will also be available. The average TDP is announced at 225 watts.
The ARC A750 Limited Edition has a chip that hosts 28 Xe Cores, 28 Ray Tracing units and 448 XMX Engines. It has 8 GB of GDDR6 in 256-bit, which translates into a bandwidth of 512 GB/s. The average TDP is also 225 watts.
As we said in our unboxing of the press kit, the two boxes are almost identical and it’s only the reference on the front panel that distinguishes them.
Bundle:
This one is non-existent except for some information leaflets and a thank you for the purchase of an ARC graphics card. Intel is cutting costs and can thus afford to keep its competitive pricing logic.
There is however a USB cable present in the box of the A770 version that will allow you to synchronize the RGB with the other components benefiting from an RGB backlight in your configuration. On the other hand, we received a very nice press bundle that you can discover here.
The cooling :
The two graphics cards we received are ” Limited Edition ” models. We will come back later on the difference between these versions and the others. The two boxes containing the GPU are perfectly identical except for the model number.
So we will limit ourselves to a series of photos of either one or the other to illustrate the features of these models. The card has two 85mm fans with 15 blades each. In terms of length, the card measures 267 mm and will occupy a width of two slots on your motherboard via a USB port.
To power this GPU, you will need an 8-pin and a 6-pin connector. Intel keeps traditional power connectors and that’s good. We can see on the right picture below the small USB connector that should allow the synchronization of the RGB with your other components when connected to your motherboard.
Design wise , it’s sober but very efficient. The card plays on black and anthracite colors. We have no doubt that modders will have a great time customizing these models. On the front panel, there are no inscriptions or logos, even on the central part of the fans. It is only on the top edge that it says “Intel ARC” and on the backplate where it says the model of the card.
The build quality is excellent and we really like the wrap around finish on the back of the card. This allows to make the connection between the front panel and the backplate. There are four outputs, three DisplayPort 2.0 and one HDMI 2.1. As for the prices that have already been revealed, we are talking about an ARC A770 16 GB starting at $ 329 and an ARC A750 at $289. With European taxes, we should be around 400/425 euros for the A770 but nothing is confirmed yet.
Radiator:
At the time of posting this article, we have not yet disassembled our samples for the simple reason that we did not know where to start this operation. Since then, we have seen our colleagues from Mydrivers who have stripped down their ARC A750 and ARC 770 samples. So we will use the pictures from their site.
We can discover the cooling system which is actually a vapor chamber that will be in charge of dissipating the heat of the different components. The copper part is in contact with the GPU chip via thermal paste and via thermal pads for the memory chips and the power stage.
This vapor chamber is associated with four copper heat pipes and connected to the radiator to optimize heat dissipation. The radiator is integrated into the vapor chamber. We will judge the performance of this cooling system which uses only 2 slots of thickness.
Yes, some backlighting:
But only on the ARC A770 version, the A750 does not have RGB backlighting and sees it replaced by a metallic border. The ARC A770 Limited Edition has four areas with RGB: around the two fans, on the top edge of the card as well as the “Intel ARC” logo and finally on part of the backplate.
Personally, but it’s a matter of taste, I find it much prettier without backlighting, it’s a bit too much or just in white.
The connectors:
To power the card, there is an 8-pin and a 6-pin connector. These are traditional connectors found on most power supplies. The card has three DisplayPort video outputs and an HDMI 2.1 port.
The bracket is perforated to let the heat escape under the pressure of the two fans. Now that we’ve had a good look at it, let’s move on to the insides of the card.
