BOTTLENECKING

Hi,

I've been resarching for a long time now. I want to use an EGPU to boost my Lenovo Ideapad 110-15ISK's (i3 6006u, 8 GB DDR4 RAM) perforance. What I'm not sure about is bottlenecking; is it fine to use a GTX 960 (even though it will bottleneck for sure due to the CPU) instead of a GTX 750 Ti, or is an unbottlenecked GPU way more usefull?

Wouldn't they perform the same until I play a GPU intensive game? And, if so, isn't the GTX 960 the smarter choice?
Thanks

1. Bottlenecking does not mean that your machine will fail to eek out more value with a more powerful GPU. It's more like having a score multiplier turned down, somewhere in your equation. It's real, but it's misunderstood and way less of an issue than folks tend to make it out to be. 

My i3-4030u performs better with my GTX 1060 than it does with the GTX 750 Ti. The bottleneck range is certainly somewhere between those two, but a stronger card still yeilds better net frames at more consistently higher settings. 

2. You use a GTX 750 Ti, 1050 Ti, or 1650 Ti in specific settings where power/thermals/space/simplicity are the single most compelling factor in your equation. I would choose a low-watt GTX **50 series card because it gets all of its power from the PCIe bus, and reduces a whole lot of complicated questions (having to worry about power overhead from your PSU, foremost).  I would choose a GTX **60 card because (a ) I can afford to and because (b ) available power isn't limited.

3. If you have both available, the GTX 960 would give you consistently stronger performance, and [both are Maxwell series cards]. Don't let "Bottlenecking" fears hold you back.

Firstly, thank you for answering.

Let's suppose an ideal scenario where I have money, space isn't an issue and psu's aren't a deal because I can also afford one. This is kind of my actual situation; now I know what bottlenecking really means, in terms of eGPU's, I'll go for a 960. Might the 970 be a better choice for someone like me (remember, I can afford it), or should I stick with a *60?

To be honest, I'm looking for a card which allows me to test how well this graphic-card-style will perform. And, as you said your 1060 worked fine with such a CPU, I'll give it a try if everything goes fine.

Edit** Would you mind giving me the fps you get while playing highly-demanding titles with the 1060? 🙂

Hey, @anonimo_rodriguez! Let me know if this web link works for you ... as I currently hold 100% of the benchmark scores for the i3-4030U and the i7-5600U CPU's paired with a 1060 card. 🙂
1st/3rd results are with a straight PCIe 1x-->16x riser, and the 2nd/4th results were with a GDC EXP Beast v8.x.

Some games maintain 60FPS with some frame drops, on the i3, but I mostly play older titles and my i3 system is old, only has 4GB memory, etc etc... general consensus is that the 1060 is the upper limit for bottlenecking this link, and the GTX 970 would offer comparable horsepower.

FYI, while I score above 99% nominal performance over the straight PCIe riser on a desktop, the Beast seems to consume a lot more overhead and my theory is that it's not consistently getting Gen2 signaling.

Still, it's all worth it over stock graphics.

I plan to more systematically benchmark my available GPU's but suffice to say, better GPU gives better FPS even with the same/weak CPU.

I'll go for a 970 and, if after benchmarking and testingI feel like a 1060 could do... well, I'll make the beast roar!

Hehe, thank you very much for your support.

Please, please PLEASE post results. DIY eGPU's have grown to be my obsession and would love to hear what works/doesn't work for you. You have a community of nerds, here, interested in what you build next!

Update!!

Managed to get a brand new Asus Turbo OC 970 4gb for 90€!!!, a PSU for 50€ and the adapter for 40€. They'll arrive next week, so I just need to wait. I'm so excited! 🙂
