what's difference between Gk104 and 106?

[JTsyo]

Comparing the 660 to 660Ti. Other than the lower shader and such is there much difference between the chips? I'm upgrading from a 260 so both will be a good step up. the 660 seems to be the better value and able to run BF3 on ultra at 1080.

on both counts you are correct however, you're better off with a 7870 it's better across a wider range of games and oc's better as well http://www.xbitlabs.com/picture/?src=/images/graphics/geforce-gtx-660/zfulltable.png

7870 does not support PhysX. That means he will not get all the cool extra effects in games like Borderlands 2.

I find the 660Ti a strange one. I feel it has no place in the market. Either go for a GTX 660, which is much value and will suffice for most when 1080dpi, or go straight to the GTX 670.

I'm sticking with nVidia since that's what I've used for the last 4 cards.

Was hoping for a price drop in the Ti that would make it a better value but not sure how far it would have to drop to pay for that 10% boost over the 660. I wanted to be sure I wasn't missing some feature between the two chips.

you would be since physX requires a powerful card so if bl2/ batman ac with physX was important along with good frames and iq settings then the 660ti would have to be your choice however brand loyalty even though the other side has better options is not a smart move it hurts the market and prices for both sides

are you really considering a 660 when a custom 7950 sells for only 50$ more?

anyway, I do not think you will lose any features going with gk106 vs gk104

You are talking about the differences between a cutdown chip and a full feature one.

the difference is listed here:

[blastingcap]

The difference between 104 and 106 is 2.

Sorry, I couldn't resist.

Which do you consider cut down? The 660 with less shader cores or the Ti which has the memory cut down to 192?

both have 192 bit memory

 

[Lepton87]

Both card are severely bandwidth crippled and that 2Gb memory capacity is shady at best which only exacerbate bandwidth issues. Has anyone compared GTX460 192bit with equal memory frequency to GTX660? I'm talking about a synthetic test that only scales with memory bandwidth, as far as I remember 3dmark 06 has such a test. Should be interesting to see the results. Either GTX660 has all around worse bandwidth that it could have(very bad on an already bandwidth starved card) or 1.5GB is only usable with decent speed, the remaining 512mb is for marketing reasons. If you really want one of those unbalanced cards, pick 660 if it's more than 15% cheaper than 660Ti, if not pick 660TI.

The GK106 GPU that powers the GTX660 is the mainstream part where the GK104 is the enthusiast part. Nvidia disabled certain sections of the GK104 chip (called binning during production) to improve yields and put these binned GK104s in the GTX660 Ti.

That's more or less accurate, but binning and harvesting are different things. Binned parts can have the same number of SMX's but clocked lower or higher than the designated stock speed, for example.

From what I've read, you get OK performance up to 1.5G and then a slow down but you're still better off than with just 1.5G.

 

[JTsyo]

yes but the 660 can only go to 192 while the Ti has be disabled down to 192.

Does the 3GB versions fix this or will they still go slower after 1.5G?

lol, why are you asking yourself a question?

and I really wish the nonsense about the card performing well until it uses 1.5gb of vram would stop. that is false and there is not a single bit of proof to back that up.

I have a 192bit bus with 1gb of vram and my card scales just fine and there is no drop off past 768mb at all.

just quoted that to follow along that line of thinking. I couldn't find where I read about 1.5G limit and then the bit slower for the other 512 meg. But I did find the answer to my previous question in Tom's article about 660Ti memory.

Giving the GeForce GTX 660 Ti another gigabyte of memory, totaling 3 GB, is pointless, though. Even games that are modified to support huge textures demonstrate worse performance with 3 GB compared to 2 GB.

 

[ShintaiDK]

The TI. The non TI is a fully functional chip without disabled parts.

Didnt 3GB cards lose to 2GB cards in benchmarks?

 

[JTsyo]

Alright, picked up Armored Kill for BF3 and about to pull the trigger on a EVGA 660 to upgrade from the GTX260 for the larger maps. Any further words on a price drop?

 

[hokies83]

Id wait for a GTX 670 Price drop or buy a used one to future proof.

Im sure you can Wheel and deal your way to a GTX 670 for 300$ then use that 260 for Physx in Borderlands 2.

 

[JTsyo]

checked with Amazon, they give a price reduction upto $20. So 660 here I come.

Get the GTX 660 Ti. It has better price perf than GTX 660. Also the GTX 660 has been handicapped by Nvidia's restrictions on Power Target.

http://www.hardocp.com/article/2012/09/19/asus_geforce_gtx_660_directcu_ii_overclocking_review/

"In the screenshot above we are showing the maximum Power Target the GTX 660 allows, 10% (110 on the slider over 100) from the base. This is by far the lowest Power Target percentage of any Kepler generation GPU to date. On the higher-end GK104 GPUs the Power Target can be set to +20% and here we are only able to set +10%. We already explained above that at 1084MHz it is operating 5% above the Boost clock, already eating up some of our Power Target room. With only +10% Power Target, we aren't going to have the power needed to allow stable high overclocks, and our tests proved that. We have data that outlines all this."

http://www.hardocp.com/article/2012/09/19/asus_geforce_gtx_660_directcu_ii_overclocking_review/5

"The GTX 660 is not an overclocker’s GPU. It isn't the fault of ASUS however. It is the NVIDIA specified strict limit to the Power Target that is keeping us from achieving good overclocks. If some manufacturer were to come out with a custom GTX 660 that is able to provide us a higher Power Target, we could see some great overclocks out of this GPU. Unfortunately this kind of thing is frowned upon this generation by NVIDIA. NVIDIA is being very strict on the TDP, Power Target, and overvoltage with the Kepler generation. Perhaps NVIDIA is trying to keep RMAs and support calls down compared to the last couple of generations or perhaps going to greater lengths to stratify its product stack? The point is, for us enthusiast overclockers the GTX 660 is one of the most strictly capped GPU generations to date when it comes to overclocking abilities."

here is the GTX 660 Ti OC
