GTX 680 can be flashed to a 770

[bystander36]

I'm wondering if the 770 has higher voltage, or no longer locks the voltage. This would be the only advantage to flashing to a 770 that I can think of.

570 had less raster units than 480. 48 vs. 40.

I doubt it, just a mild OC and Boost 2.0 is my guess.

And rumors are putting the 4 GB edition at the price of the current 2 GB - that would be awesome if true.

unless there is some hidden features on the 770. 680 oc is fine as it is.

as for the price question. expect $50 to $100 over 680 pricing.

The gtx570 was a rebadged gtx480. What's your point?

That's not even remotely close.

1. Completely different silicon.
- They changed the composition of transistor types from GF100 to GF110 to lower GF110’s leakage at higher clocks
- GTX 570 could retire twice as many FP16 texels per clock as GTX 480, and it also featured NVIDIA’s improved Z-culling system.

2. Completely different specs
- 320-bit bus vs. 384-bit
- 1.28GB VRAM vs. 1.5GB
- 40 ROPs vs. 48 ROPs.

GTX770 seems to be GTX680 with slightly changed clocks and nothing more. It's similar to HD7970 --> HD7970GE. The most exciting aspect will be Titan's cooler and a possible price drop to $399.

as for the price question. expect $50 to $100 over 680 pricing.

That would be an automatic fail to release a barely faster GTX680 for $50-100 more 1 year later. That would be the biggest slap in the face. 5-10% faster GTX770 4GB should be $399 at most as hardware from the same generation should drop in price and get faster over time. It's extremely disingenuous to even call this series GTX7xx. NV is throwing the generational convention straight out the window like they magically introduced GeForce 9. That series didn't deserve GeForce 9 moniker either.

Are you referring to 770 pricing? They won't do this. See thread at top of page for an explanation.

He He and still no New chip ahh lol and no DX11.1 or Full DX11.x and when Watch Dogs and Battlefiel 4 arrives you don't have all visuals and Performance loss ;-) i still prefer Radeon

What visual enhancements does DX11.1 provide over DX11.0? Also, how do you know there will be a performance loss with DX11 vs. DX11.1 in those titles? Aren't you also assuming that NV cards will run those games slower but we haven't seen any benchmarks to assume that.

So you like all those extra bells and whistles then?

 

[Rvenger]

DX 11.1 and 11.0 differences still remain undetermined.

I've seen repi mention on his twitter that DX11.1 is being used to reduce the CPU overhead in BF4.

If there's something "big" in DX11.1 though, it could be possible for Nvidia to support that. Nvidia supported the DX10.1 features in Far Cry 2, and Just Cause 2 also had support for the DX10.1 features possible on Nvidia's hardware.

 

[bystander36]

From my understanding, Nvidia supports much if not most of DX 11.1, just not all of it. From what I've heard, it is some of the OpenCl/DirectCompute stuff that isn't supported. So if it is a problem or not depends on what is used.

 

[omeds]

I remember reading they support all gaming related features of DX11.1.

 

[Nintendesert]

I just flashed my GTX680 to a GTX9000!

I can't believe the performance!

We will find out once these features are offered. Nvidia never made any concrete statements or gave any specifics.

Not only that, but you don't need to upgrade for at least 2 more years. :thumbsup:

 

[lavaheadache]

what would truly be great is to flash a Titan to a Titan Ultra.

Reply directly from NVIDIA:

• Partial constant buffer updates
• Logic operations in the Output Merger
• 16bpp rendering
• UAV-only rendering
• Partial clears
• Large constant buffers

We did not enable four non-gaming features in Hardware in Kepler (for 11_1):

• Target-Independent Rasterization (2D rendering only)
• 16xMSAA Rasterization (2D rendering only)
• Orthogonal Line Rendering Mode
• UAV in non-pixel-shader stages

So basically, NVIDIA does support 11.1 features with 11_0 feature level through the DirectX 11.1 API.
"We do not support feature level 11_1. This is a bit confusing, due to Microsoft naming. So we do support 11.1 from a feature level for gaming related features."

There's nothing confusing. nVidia is claiming 11.1 support on a technicality. They do not support the full 11.1 feature set, which is 11_1. That's the bottom line.
