Complete Nvidia Kepler GPU Lineup Leaked

By - Source: EXPreview | B 13 comments

Leaked information has appeared on the internet with first detailed information on the upcoming Nvidia Kepler (GeForce 600) series graphics cards, which are set to release in April/May time frame.

Unlike with the AMD Radeon HD 7000 series, the Nvidia has kept it very quiet with regards to information being leaked on its upcoming Kepler series graphics cards. Website Lenzfire has published specifications for the upcoming Kepler series. As with all leaked information, all unofficial sources should be taken with a grain of salt.

With the chart listed below, we see see the entire lineup of Kepler cards from the flagship Nvidia GTX 690 dual GPU to the GTX 640.  The die size in the higher end GeForce cards are approximately 50 percent larger than that of the AMD Radeon HD 7970 (550mm2 vs 365mm2), while only 30mm2 larger than its GF110 predecessor (GTX 580).

In the chart below, we get details on price points, release dates and expected performance scale compared to current Nvidia GPUs and AMD's HD 7000 series. Based on the performance numbers, the GTX 680 is set to show a 45 percent performance increase over the HD 7970, while the GTX 670 shows a 20 percent improvement. If the numbers are true, this would be a nice win for Nvidia's Kepler against AMD's new Graphics Core Next architecture. The GTX 660 Ti is set to show a 10 percent improvement over the HD 7950 in the current battle of price to performance ratio. Though we don't have estimated performance numbers for AMD's HD 78xx or 77xx series, Nvidia's budget-friendly cards stack up nicely to its current high-end graphics cards.

Do you think Nvidia's Kepler will live up to the alleged performance figures and regain the performance crown from AMD?

    Seems good so far, but as with everything, only the benchmarks are a true test of mettle.

    some are calling these fakes due to the so called hot clocking of the shaders, but i'm not sure if the lack of hot clocking is also a rumour that has not been proven.
    Guess we'll have to wait and see.

    I wont say they cant be right but there is plenty there that makes me doubt they are.

    the 224 to 256bit interface jump is fishy, i'd love that it would be right, with the performance that we've been seeing, but who knows.

    do they come in AGP?

    these cards are pci-e 3. AGPx8 has only got 2100mb/s

    Will I miss out on performance if I only have a pcie 2 board? I have 2 x 570's now and would like to upgrade when these cards release. If I need a pcie 3 board I will probably wait another year.

    a 570 nearly saturates pci-e x8, so a replacement will need more than 8 lanes, pci-e3 x8 will have twice the bandwidth and therefore will not be saturated, so unless you can run pci-e2 x16/x16 on your current mobo you will be constrained a bit (but only a bit)

    Thanks, I have pcie 2 x16/x16 so should be ok

    I would think so yes.

    Happy there is some decent competition in the GPU sector, can't wait for Kepler so 7xxx prices go down. Let the price wars begin :)
