GTX 860M vs GTX 770M vs GT 755 SLI: Same power, same price, way lower power consumption

Hi buddies and buddesses (is that how you write it?)

In this post we’ll cover how goes the new Maxwell GTX 860M vs GTX 770M (older Kepler) and the GT 755M SLI (or GT 750M SLI). I’ve already talked about the GTX 860M in the previous post about GTX 860M vs GTX 765M, which was the high midrange king before it. The 755M SLI and the GTX 770M were competing more or less on the same price square of $1000-$1200, delivering the same performance more or less (average advantage for the SI). The 755M SLI (Y510p) selling for $900-$1000, delivering the highest gaming performance under $1100-$1200, making it a very cost effective solution for gamers.

In many games, the 860M has a very significant 50% advantage over the GTX 765M, doing it for the same price and for less energy. There is no question the 860M is way better than the 765M. In this post we’ll see that the 860M love for power efficiency and performance per price does not stop there, but also sails into the lands of the GTX 770M and the popular GT 750M / 755M SLI inside the Lenovo Y510p.

Lets start again with some tables:

Model core (stock) memory (stock) Power
GTX 770M (Kepler) GK106 (Kepler), 960 cores@800MHZ + boost GDDR5@1.0GHZ (4MHZ effective), 192-bit around 75W
GTX 860M (Maxwell) GM104 (Maxwell), 640 cores@1030MHZ + boost GDDR5@1.25GHZ (5GHZ effective), 128-bit probably around 40W-45W
GT 755M SLI GK107 (Kepler), 2×384 cores@960MHZ + boost GDDR5@1350MHZ (5400MHZ effective), 128-bit 2x 45W-50W

* The GTX 860M power consumption specifications are based on the desktop GTX 750 Ti measures compared to the desktop GT 650 Ti (here), combined with the fact that the GTX 765M has a power consumption of around 60W. The GTX 750 Ti (640 cores, around the same clocks) have maximal power draw around 25-30W lower than the GTX 650 Ti, which is a bit faster than the GTX 765M but not by much. Therefore, I think the power consumption of the Maxwell GTX 860M should be around 20-25W less than the GTX 765M.

It is quite obvious that the GTX 860M GPU has a significantly lower power consumption, especially compared to the SLI configuration in the very popular Lenovo Y510, since the Y510p was selling for around $900-$1000, offering the highest gaming performance in this price range which was otherwise filled with GTX 765M offerings. The GTX 770M was usually selling for around $1200 at lowest, including OS.

This comparison is important since as I said, the SLI and 770M were competing in the same price square, with a significant advantage for the Y510p / 755M SLI in terms of performance per price, but also consumes a lot of energy and produced a lot of heat.

OK, enough talking. lets see some numbers. Numbers are for gaming on very high settings @ 1080p (GTX 860M numbers source):

GTX 860M vs GTX 770M vs GT 755M SLI

And the table

GTX 860M (Maxwell) GTX 770M GT 755M SLI GTX 765M
Titanfall 42 48 34
Thief 25 27 19
CoD: Ghosts 31 28 32 21
Battlefield 4 29 28 32 20
Dota 2 83 76 66 52
Metro: Last Light 29 27 25 19
Tomb Raider 45 44 51 33
Crysis 3 19 20 20 15

Well, what do we see? The GTX 860M is more or less on the same level of the GTX 770M, sometimes faster and sometimes slower, but all the numbers are very close to each other. The GTX 770M draws a lot more power and produces more heat. A GTX 860M is without any question a much superior solution (good job Nvidia for delivering and a spank for holding it back in order to squeeze more money).

The 755M SLI is still the Joker of these three, however, anyone who used the Y510p knows how hot it got – the I7 /I5 inside was running on the base 2.4GHZ while gaming in almost any case, rendering the CPU less than its potential. Therefore, a GTX 860M in a Y510p cassis (read: Lenovo Y50) would be a very desirable offer for gamers, even if the GTX 860M will perform a bit lower than the 755M SLI. The 860M is practically half the power consumption of the SLI, under full load. It will also solve the Y510p problem of not having a functioning integrated GPU, resulting in a low battery performance.

I should mention again that the 860M should be available inside a $1000 gaming laptops, like the new Lenovo Y50. Some are already available in the form of the Sager NP7338 / Clevo W230SS for less than $1000 and more for higher price.

Finally, if you are reading it around March or April 2014, you better wait with a purchase – let some more laptops come up and let the competition begin.

    Great summary.

    I love the technical expertise put in this.

    Hey junky, I got a question. I’m trying to pick out a laptop that can give me the best smooth performance that will give me the least input lag as possible (im a pretty serious gamer). I play a lot of TF2 and CS:GO. I tried the G750JM and it did a pretty good job at this, but i returned it because it was too heavy and instead got an Alienware 13. I regret all of this. I guess its true what people say about how a TN screen has a much faster response time than a IPS screen? Anyway I’m right now i want to get a G750 back, so I’m choosing between a G750JH with no SSD that I can get for $1000 with a backpack, or a G750JM with a 256gb SSD + backpack for the same price. Mean reason I’m leaning towards the JH is because its screen refresh rate can be increased to 100hz. And I think i have a lone m.2 128gb ssd lying around so I can just buy an M.2 adapter board and put it in there. What do you suggest? Saving as much money as possible is pretty important to me, and I’m also maybe considering a G551JW; I’m just not sure if it’ll give me the smooth experience I’m looking for. I’ll be using them for when I enter college in a couple months.

    • Hi!

      1. What are your needs?
      2. Why not 15.6″?
      3. Can you use the forums?

      • Marc

        Hey, what exactly do you mean? I play different source games and also worth with 3d cad software. I could go with the 15″ but I’ve never dealt with that specific one before. I don’t know anything about it and I hear the trackpad is terrible. I’m all about build quality.
        And… which forums?

        • These forums:
          15.6″ is only a screen size – there are many models

          • Marc

            No 15 inch has interested me so far besides that asus maybe. I’ve done plenty of research and I think a 17 inch would suit me best. I’m just want to know whether you think the 780m is worth it in the JH over an 860m with an ssd. If you know of any nice 15″ I may have missed feel free to inform me.

            • 780M is not a good GPU, but can we continue it over the forums?

        I have been doing the great laptop rotation for some time now. I’m pretty set on a y50 as I returned a y40 (crap performance) then bought a y410p (meh resolution, need 1080p although love the 1tb and m.2 128gb ssd combo) then bought and returned a y510p 750m sli (most of my games performed like crap with that sli setup). I’d really like an msi laptop (neat keyboard m.2 port for hhd and ssd combo) I want th best performing laptop I can get for $1k. ($1k being max budgeted) if possible I think an hdmi IN would be AWESOME! But I’m mostly going to be gaming. Really looking at y50 with 4gb vram because of battlefield (and other games) being a vram hog. Sorry for bad formatting, just not my strong suite.

        • 1. which MSI?
          2. Not sure the 4GB is really useful. Remember that the much much faster 970M uses only 3GB… if you see benchmarks that it shows the 4GB version are better, keep in mind it might be inefficiency of the game and might be fixed in the future
          3. you have mini display ports also
          4. Can you please open a thread on the forums?

          • Drake Timothy Roediger

            Opening a thread on the forums now.

      • Drake Timothy Roediger

        Also on that laptop should be like 900$ on sometime in the future.
