GeForce GT 640, GTX 650 Coming in May, GTX 660 Specifications

GeForce GT 640, GTX 650 Coming in May, GTX 660 Specifications geforce gtx 685 geforce gtx 670ti geforce gtx 670 geforce gtx 660 geforce gtx 650ti geforce gt 640
According to multiple sources NVIDIA may release new cards for mid-range market based on GK107 in May, along with GTX 670 Ti/non-Ti based on GK104.

Specifications of mid-range GPUs are clarifying. NVIDIA will release two cards based on GK107 GPU, one with GDDR5 memory and the other with GDDR3 memory. Those cards will most likely replace current GTX 550 Ti. They will be named respectively GTX 650 and GT 640. GK107 will have 384 CUDA cores, but the count of TMUs and ROPs is not yet revealed. We can expect those cards in May. These cards should be priced around €100.

3DCenter has posted specifications of GK106 GPU, which will likely power graphics card named GTX 660. It will pack 768 CUDA cores with 64 texture and 24 raster operating units. It will most likely have 192-bit memory interface and be equipped with 1.5 of 2GB of GDDR5 memory. This card will be released in summer for around €200.

There are no specifications of the rest cards based on GK104 core yet. Those cards are GTX 670 Ti, GTX 670 and GTX 690. First two should be available in May. GTX 670 Ti will be priced at £320 (around €380/$390) and GTX 670 will have a price tag of £240 (~€290/$300). Even though these cards are based on GK104 GPU (same as GTX 680) it is unknown if they will feature same number of CUDA cores and TMUs/ROPs. They will most likely have reduced CUDA cores or at least lower overclocking capabilities.

We still look forward to first leaks regarding GK110 GPU. Card which was originally to replace GTX 580, was shifted to later date. It would have 2304 CUDA cores and most likely leave all the competition (from own backyard) behind. NVIDIA will surely analyze how releasing of GTX 680 4GB will impact whole market. Then plans for GK110 may even be abandoned.

    amd hd7850 will not reduce price, see the time nvidia gtx 660 release time

  • BestJinjo

    Yup. That’s why it’s the worst time to upgrade right now. HD7850 is barely better than an HD6950 more than a year later for $250+. Terrible value. 

  • Aloevera

    gtx 660 will be slower than hd7850 but price will be under 200$ i gues. . .
    gtx 670 will be better than hd7850 but slower than hd7870 for the price of 250$ ?
    gtx670Ti OC and more shader version will be just a tad better than hd7950 for under 400$ ?
    But anyway in my eyes 7870 should be 250& and 7850 should be 180$ if you look performanc that is still like last gen lol

     NVIDIA will make a lot of profit thanks to GTX 680. Card much more innovative and futureproof than HD 7970. Who cares if 7970 can be overclocked by 30%, when you will be able to buy additional VRM section for GTX 680 and increase it’s clocks by 40-50%. ZOTAC comes with 2GHz core clock, and we still have no idea how will 4GB model impact whole market. Nevertheless NVIDIA may raise prices of its products because people with grab them as soon as they hit markets. Anyway, these are only rumors and prices are not yet official.

  • Tackle70

     A 2 GHz GTX 680 is a pipe dream rumor until we actually see some official info on it.

    Nobody has EVER to my knowledge even come close to releasing a GPU with a ~100% factory overclock on it, let alone doing that on air. It’s not possible… current GTX 680 boards don’t even get close to that on LN2. I’ll believe it when I see it and everyone else should too. It’s kinda ignorant to assume its existence based on rumored releases IMO.

  • http://videocardz.com VideoCardz

     It will feature additional VRM Phases, new PCB na most likely more memory. It IS possible :) Maybe NVIDIA was working on new sample of GK104 GPU, or maybe it will not be GK104 anyway? What we know for sure is the fact that ZOTAC has released information that they are goind to release such gpu. Just wait.

  • Tackle70

     Keep dreamin… better VRM + PCB =/= 100% increase in possible clock speeds on air. If they do this, it will be a historic achievement for GPU manufacturers; nothing even close has ever been done. Most likely, they will release a GPU that *can* reach 2 GHz on LN2, not one that is factory clocked to such an insane level on air (which involves so many physical limitations and problems that I can’t believe people are taking it seriously).

     And yeah… what did I tell you:
    http://videocardz.com/31645/zotac-geforce-gtx-680-extreme-edition-features-1-2ghz-clock

    It’s a ~20% overclock that might be able to hit 2 GHz on something crazy like LN2. Nice, but nothing all that noteworthy.

  • Mufa_gwef

    I think the 2GHz rumour was the case of ‘Chinese whispers’. Someone heard that it may be able to reach that at the very extremes of the overclocking crowd (possible but relevant to only 0.001% of the GPU market) however it ended up becoming a rumour about a 2GHz production card and on air. I’ve seen so much of this over the past few months with all the rumours that came out my advice would be to take everything with a pinch of salt rather than to invest in it as fact until the true facts come to light – I know sometimes its nice to dream though ;)

    the rule of performance doubling every 1.5 years doesn’t really stand up :-s
