Gigabyte Working on Radeon HD 5870 1 GHz Super Overclock Model

Gigabyte is expanding its Super Overclock family of graphics cards with a highly tweaked model based on the ATI Radeon HD 5870. The Gigabyte GV-R587SO-1GD features a complete design overhaul over AMD's reference design, with the card sporting a typical Gigabyte-blue colored PCB, and a custom-design double-slot VGA cooler. The PCB uses Gigabyte's Ultra Durable VGA construction which makes use of a PCB with 2 oz copper layer, ferrite core chokes, low RDS (on) MOSFETs, and Japanese solid-state capacitors. The VGA cooler consists of a GPU base from which four copper heat pipes convey heat to aluminum fin blocks cooled by two 90 mm fans.

The GV-R587SO-1GD comes with out of the box clock speeds of 1000 MHz (core), and 1300 MHz / 5.20 GHz effective (memory), against reference AMD clock speeds of 850 MHz (core) and 1200 MHz / 4.80 GHz (memory). ATI Eyefinity support is retained with a display connectivity that resembles the reference design: two DVI-D, and one each of DisplayPort and HDMI. The GPU features DirectX 11 compliance, 1600 stream processors, and a 256-bit wide GDDR5 memory interface. It connects to 1 GB of memory.

That'd be wicked sexy on my p55-ud3r.

I wouldn't be surprised if ATi do this and call it a 5890.

The fact that there's 1 GHz HD 5870s shows that there won't be an HD 5890.

I disagree, there bound to be a batch of chips that are screaming and go up even further, it be silly of AMD not to bin them higher and sell them as another GPU.


It would not make sense if they didn't at the very least :laugh:

I disagree. It's not like HD 4890 was made out of "a batch of chips that were screaming and go up even further", they were made out of a redesigned ASIC. RV770 couldn't reach those speeds, so they made the new ASIC and a new product. Cypress is able to handle those speeds, so no new product.

Not sure how efficient the cooling would be on that card, especially considering the air expulsion isn't directed out of the case, like you would normally find, but rather, bouncing off the connectors. I'm sure this would have some effect on the airflow, or adverse affect on the air temp within a case?

I thought they were still the same GPU with only one minor difference to allow to higher clock speeds?


That sounds like a modified higher bined chip to me.


Also your logic" cypress can handle those speeds" its almost like you don't work on an enthusiast site.

things don't stop because they're enough ! you know that :p

I'm expecting a 5890 eventually.

Yeah panther, but there's also those out there that want these speeds as "stock." Those that aren't OC enthusiasts like us.:D

I know, but theres bound to be some crazy guy at ati who fancies 1200mhz cards :P

It was a different chip, with the same specifications, but with the ability to handle higher clock speeds.

Aside from that being incorrect, you're contradicting yourself. If it's modified (physically), it can't be 'higher binned', and vice versa.

No, it's not like that. All that was said is there's no need for AMD to make a GPU when the existing one reaches high clock speeds. RV770 couldn't reach high clock speeds need to make any real "OC" versions, like Cypress is allowing AIBs to make (example: this card). Also, stick to the argument, cut the crap with getting personal to make points.

Btarunr maybe right that we won't see a 5890, but I wouldn't be surprised if it is just a 1GHz cored 5870 rebranded.

Not necessarily change silicon the same , change components on the pcb the chip is attached to.

Admittedly I've no idea about if the silicon its selfs is any different, I would of thought especially producing a new gpu just for one card be damn expensive though.


Still holding on out for 5890, especially if nvidias new chip is faster.

If you mean to say that they will use the same core and rebrand it, then it's not the case. Gigabyte is calling this card an HD 5870 Super Overclock.

MSI's HD 5870 Lightning runs at 1 GHz, too.

Once again, HD 4890 was a one off case. RV770 just couldn't reach high clock speeds, and AMD needed a GPU which could, with minimal R&D involved. There was no HD 3890, nothing between "Pro" and "XT(X)" in the previous generations, either.

I know that, but I'm saying it's not out of the realms of possibility that a 5890 may emerge. I doubt they'd release a 512 bit bus 5890 so a super overclocked version of 5870 could (no matter how unlikely it is) could come out, maybe a 2GB variant with a default core clock of 1GHz+ just with the 5890 moniker.

This would be wicked with 2GB of vmem.

Yes I know, but things change eh : ]


Hmm maybe I'm making the reason why I'm disagreeing clear.

You stated it as fact. rather then speculation.

I'd of been quite happy to pass the comment over otherwise.

Yes, the silicon itself is different, and it was the cheapest way AMD could replenish the competitiveness of its HD 4800 series after NVIDIA's 55 nm GT200. It used the RV770's essential design, redesigned its on-die power delivery mechanism, gave it a power-stabilizing decode micro-capacitor ring on the periphery of the die, etc. This stepped the transistor counts by 3 million. So it's a new ASIC, which attained high clock speeds while also being more energy efficient than RV770. There was no way RV770 could 1. Reach 1 GHz speeds on a consumer product 2. do so at acceptable power draws.

Well thanks, can't argue with being done :laugh:

Makes sense why 4890s are so expensive in relation.





I still have my fingers crossed for a 5 series version how ever.

I wouldn't be surprised if we see a new ASIC for the '5890' due to the fact the 5870 reference PCB has solder points and room for an 8-pin connector and like the 4890 could possibly use 5 phase power if it was necessary, which, looking at the TDP and draw that the current 5 series uses, is highly unlikely.

Probably waiting for nVIDIA to get something out of the door first.

That 8-pin connector on the CypressXT PCB is for the 2 GB model.

This Super overclock model in 2gb in Crossfire would be a killer setup, the 1gb's would be sweet and all, but for the price of a card that special I'd want 2gb.

MMMMM if I had a 2gb single gpu graphics card I would personally texture mod all my games just to fully utilise that memory :laugh:

HD 5870 1 GHz sounds pretty tempting . The card's price however will be a little to high for my taste , and it`s good to know that those clocks are achievable with some minor voltage bump . However if i had the money i would rather look at the HD 5870 Lightning Edition from MSI , looks a little bit better . But than again Gigabyte's version will end up cheaper . OH decisions decisions ... :)
Way to go Gigabyte !
