GTX770 Review

[MacLeod]

A couple of the reviews are saying you're probably not going to see any reference cards at retail. Not sure why tho. Wouldn't matter to me. Aftermarket coolers are better anyway but I guess it would make it easier for SLI.

 

[antihero]

You realise how close the titan and 780 are yeah? And Im not going to do 3x770

Then at least answer me this: Do you think three factory-overclocked 770s will outperform two reference model 780s?

Considering for it to run properly youd need a board with really good PCIE layout and lots of PCIE lanes..... whats the point?

Chance of getting equal or better performance for less expense so I can spend more on other parts.

Sometimes it will create more hassle and make the rig technically worse. IE 3 gpu's will get hot and noisey.... You are just being a bit narrow minded.

2 GPU's is where the sensible is at.

feel like you dad ffs.

Really Tom, I'm surprised at your intolerance. I don't see why I would spend nearly 1300€ on something without looking at other options first. You wouldn't tell someone to get a Titan just because it's the fastest single-GPU card ever, would you? I haven't bought anything yet so it's all good.

Edit:
If you can't talk to me in a way that isn't condescending then don't bother with my questions lol..

 

[tinytomlogan]

Ive explained already mate....... Plus tbh youre lucky you got a reply at all. Some of us have been working 14/16 hour days for the last 2 weeks straight........

 

[Roooker]

I would like to see more game benchmarks in future reviews..


Other than that:
THIS will give you a nice table on all the 770 available.

Rebadged 680 - Better Prices - Nuff Said

Your only gonna get titan pcb and cooler if you get nvidia reference ......

And Reference are not gonna be around untill all these fake 770s have been sold ....

(pictures galore)

Now that is the true kick in the teeth from the vendors

Look like Inno3D are the only ones using Titan reference cooler so far. Shame.

 

[FTLN]

Only one I have found so far that has updated pcb is the gigabyte windforce ............

Look like Inno3D are the only ones using Titan reference cooler so far. Shame.

Are you getting some in Rawz ?

Quick question... How come you multiply the memory clock by 4 to get the effective memory clock? What's the difference?

^^ I still don't see why you would multiply by four...

 

[qhfreddy]

I'm pretty impressed, probably am going to get one of these unless the GTX670 Sig2 comes down to around what 660 prices have been.

GDDR5 is basically "quad-channel" memory

 

[Vicey]

Incase anyone hasn't seen it yet, EVGA is offering a free backplane to all EVGA GTX 770 purchasers if you go to their website and register your card. Offer ends in July.

I think they are doing this as a way to save face since the reference NVIDIA cooler that is featured in all the reviews of the GTX 770 is not included on any of their cards.

Good of them to offer the free backplane I suppose but it is a shame the reference cooler isn't used on their cards and it looks like most OEM's are not offering it.

 

[qhfreddy]

Yeah too bad they don't I really want one of them..

GDDR5 (Graphics Double Data Rate, version 5) SGRAM is a type of high performance dynamic random-access graphics card memory designed for applications requiring high bandwidth. Unlike its predecessor, GDDR4, GDDR5 is based on DDR3 memory which has double the data lines ("DQ" lines) compared to DDR2 but GDDR5 also has 8 bit wide prefetch buffers like GDDR4.


Qimonda, a spin-off of Infineon, has demonstrated and sampled GDDR5,[1] and released a paper about the technologies behind GDDR5.[2] On May 10, 2008, Qimonda announced volume production of 512 Mib GDDR5 modules rated at 3.6 Gbit/s (900 MHz), 4.0 Gbit/s (1 GHz), and 4.5 Gbit/s (1.125 GHz).

From wiki as u can see GDDR5 4 gig has a clock speed of 1G uses double the data lines ("DQ" lines)

from memory the DDR side mean's is can write/read on both sides of the clock cycle ie: write/read when the clock is high/rise (1) or low/fall (0) effectively doubling the data rate!


Ok, so if I divide the 837Mhz clock rate into the data rate 3348 I get 4. So the GPU clock rate is multiplied by 4 to get the memory data rate, right

So far looking across the UK vendors I can't see any with the Titan cooler which after watching the review is a big letdown. I was looking at 2 770s instead of a 780 as the price is so close to go with my new haswell build but still need to wait on the nda being lifted in the boards to decide.

Thumbs up for the review Tom , up to your usual high standards just a bit sad that your joke at the start of the video seems to be actually more like what we are getting in the uk , tho that isn't your fault at all.
