    Quadro V Geforce and Desktop V Mobile GPU

    Peter Studt Level 1

      I decided to list key specs in a table to plot the 'de-tuning' done to Mobile Graphics cards compared to their desktop twins. More specifically the differing amounts applied to GTX as compared to Quadro cards. I hope the table works ok, I'm a first time user of them .

       

       

      Specification
      GTX 660GTX 660MQuadro K5000Quadro K5000M
      Memory Size2GB2GB0%4GB4GB0%
      Memory TypeGDDR5GDDR5
      GDDR5GDDR5
      Memory Interface192-bit128-bit33%256-bit256-bit0%
      Memory Bandwidth144.2GB/s64GB/s55.7%173GB/s96GB/s44.5%
      Cuda Cores96038460%1536134412.5%
      Max Power140W~50-75W*64-46%122W100W18%

      *nVidia do not list the Max Power Consumption where I was looking. If anyone can enlighten me please do! I have seen it guest at 50W and quoted as 75W at another site Here

       

      The cards I chose are arbitrary. The GTX660 because I am buying a laptop with this variant in and the K5000 because it was the only model I found showing in both categories. The values that are percentages show the amount of de-tuning.

       

      My conclusions from this are that Quadro cards are allowed to retain much of their performance in a laptop environement because they will be purchased by users less interested in Battery operation for their machine. The GTX is hit with the All-in-one watering down brush yet they still wish to use the same product number, implying similar high performance. Buyer do your research!

       

      Hope this is useful/interesting to someone.

      Peter.

          Peter,

           

          Thanks for the chart. It would be useful to add a row with "street price" for what each adds to the cost of a laptop.

           

          Selecting the Quadro K5000M over the base K3000M on Dell's M6700 configuration page adds $1340! Surely not a reasonable option for people like you looking for a $1500 laptop that will run Premiere Pro.

            I'm assuming most are familiar with the premium charged for Quadro cards here are some prices I found. The Mobile versions are not so available obviously. I agree the cost does complete the picture, I will update the table.

             

            I found two Quadro K5000M on Ebay ~$2500

            also 2 GTX660M with only 1GB of memory though (yet more hobbling) $225 - $275

            then from Newegg there are 2 Quadro K5000  $1800 - $2000

            and countless GTX 660's Around $300

            More comparable to the Quadro card is the GTX 680 from Newegg ~$500

            and from Ebay GTX 680M $750 - $840

             

            I was trying to further understand the two Lenovo laptops at the top of the PPBM5 reults for laptops.

             

            Thanks Jim,

            Peter.

              I couldn't edit the original table anymore so here it is modified.

              ~$500$750- 840
              $1800- 2000~$2500

               

              Comparing the GTX680 with the Quadro K5000 tell a slightly different story. The GTX680M is the cheapest and the least 'hobbled' of the two, except where the power is concerned, which is a good thing no doubt .

               

              The question in my mind now is, does PPro take advantage of the GTX680M as well as it does the Quadro K5000M?

                Based on the memory bandwidth, the 680M should perform marginally better and prove a much better BFTB.

                  The 680M is the clear winner of those 3 GPU's. I guess we always knew that but it makes it somewhat clearer having them side by side.

                   

                  I notice that there is a GTX 670MX and a GTX 675MX out now that have the square die of Kepler listed at nVidia, they have 960 Cuda Cores compared to the 336 and 384 of the Fermi equivalents. I found no prices except for for a MSI GT70 at Newegg. The GTX 660M is looking much more mid-range now.
