>tfw no USB 3.0 teaming eGPUs ever
Guess I have to (((upgrade))) to something with Thundermeme if I ever want to play modern games.

Shit thread m8

Hijacking the thread.
Can the t420 dedicate the nvidia card to a virtual machine? If yes, would I need a separate monitor for it?

Ok.

It's a shit meme for people with old shitpads

A 1060m laptop cost like 600 and runs every game on low at least.

>>60602008
It's popular among people who can't afford a complete desktop and already have a business grade laptop. Very common overseas as well assuming you're an Amerifag.

>>60601999
Check your BIOS for VT-d support.
VT-x won't cut it unless you're passing USB devices and running ordinary VMs.

Yes, you will need a separate monitor.

>>60602018
A 1060m laptop will also have bad BGA joints on the GPU two months after its warranty expires, while the people with old shitpads will still get eGPU upgrades on the same computer they were using 5 years ago.

>>60602043
Who buys thunderbolt? Expresscard is the easiest way and only costs $50, and who doesn't have an PSU laying around? What are you poor?

Enter your BIOS and look for an option labeled Intel Virtualization technology (VT-d) and check if it can be enabled or disabled.

M6600 user here.
Yer rong.

Is expresscard the best shit laptop users will get?

>>60603310
No there are mPCIe, M.2, thunderbolt, all of those are viable options if the laptop supports them.

>>60603310
That would be thunderbolt.

Some days I go to college for 12 hours straight so I have to sit in the library and play shitty old games because I cant go back home. Is it a dumb idea to make an enclosure that sits under my laptop that contains the GPU, a PSU and the mini pci cable that goes to the card?

>>60604903
you could use the opportunity to read some books?
yeah that would work fine

I want to do this, but i dont have a card lying around. Should i get a 1060 for eGPU or go used?

>>60604982
You get like 30% loss in efficiency and need an external monitor.

>>60604990
I already have an external monitor and a 30% loss doesnt bother me because the most graphically intensive game i own is fallout 4. I just want to have more then 15 fps on low/medium and to not have ets2 lag in cities as much.

>>60603310
>>60604990

ExpressCard is a piece of shit and caps out at PCIe 2.0 x2 I believe. However it won't bottleneck that bad if you are using your native screen, although using your native screen requires Optimus.

Again, when you go Akito or use the Razer Core or some bullshit like that the overhead is minimal because the bandwidth is absolutely enormous. You don't need an external monitor if you have an nVidia card and Optimus installed; Bumblebee works fine on Linux as well too. Main problem is that your CPU will bottleneck in a lot of situations as cooling solutions are god awful in modern laptops.

how hard would it be to make an eGPU that uses usb-c to power itself and also connect to the computer?

>>60602449
My man those dell are built to last. Sold mine on eBay so I could build three desktops for the family.

Genuine question, why is this still a thing?

A few years back, you had some serious lack of option on mini-ITX cases/motherboards, but now there are quite a lot of them. A mini-ITX case isn't that much bigger than the EGPU enclosure and PSU.

>>60605984
People who are so poor that they play with GPUs so bad, they won't bottleneck at PCIe 2.0 x2. See people who recommend ExpressCard >>60602061
Also the same people who call other people poor.

>>60606019
I still think that you will do better with I don't know, something dirt-cheap like a current-gen Pentium and a 1050 on a mini-ITX case than with an EGPU setup, but to each their own.

>>60605984
>>60606019
It's actually amazing that people are still incapable of seeing the obvious advantages of the egpu concept. You guys seriously impress me with how dense you are.

>>60606057
You're exactly right, but they have shit for brains and can't think straight.

>>60606099
What advantages?

>>60606099
You can't see the multiple long term advantages and savings of owning a system such as >>60606057 because you only care about what you spend in the present. According to this thread's argument, the only cheap way is a PCI-e 2x expresscard which is a fucking joke when looking into the future.

I use to use a egpu with my thinkpad t400s and it was pretty good. To be honest if you put everything on high you'll get better frame rates because less stuff is being offloaded to the cpu. Until someone makes a cheap thunderbolt set up expresscard is king. I think I bought my kit for $30 and bought a used psu for like $15 on craigslist.

I don't know who the hell is going to spend $500 on a Razer Meme.

Serious question why is there no egpu for usb 3.0? It has a higher bandwidth than express card doesn't it?

>>60606132
T400? Isn't that a Core 2 Duo? What kind of performance are you usually getting?

>>60606106
In most cases, it allows you to eliminate the need and hassle of maintaining a desktop for power and a laptop for portability.

A current Kaby Lake mobile quad-core is within around 10% of the performance of the desktop range. You're able to get desktop-level CPU performance in fairly lightweight devices with excellent battery life.

However, a laptop with both a strong CPU and GPU still ends up being excessively bulky, disproportionately costly, and still lacking the same level of GPU power available on a desktop (although the 10XX series is closer than ever).

With an external GPU running at PCI-E x4 3.0, you're able to have full desktop-level CPU and GPU performance when docked with the GPU, and then disconnect the GPU to regain full portability while still taking all your data with you and avoiding the need to synchronize software/data across multiple machines. If you need to bring the GPU enclosure with you, it's still reasonably portable compared to larger laptops.

It should't be thought of primarily as a ghetto solution for people without enough money for a better desktop/laptop, although it can be helpful to them. The real utility is the convenience of consolidating the laptop/desktop into one machine with minimal compromise.

>>60606282
>A current Kaby Lake mobile quad-core is within around 10% of the performance of the desktop range.

But mostly everyone here is talking about adding ExpressCard GPUs to their Sandy/Ivy Bridge and laptops.

what egpu would I match with 2520m?
something on the cheaper side that wouldn't be hindered by this setup so much
I plan to do lots of hashes.

>>60601970

I really wanted to do an eGPU setup for my laptop for so long.

Unfortunately it's a thunderbolt 1.0 device and there is no cheap solution for this.

I was hoping the chinks would have made something but no.

Anyone try an egpu on an inspiron 15 7559? apparently need a NGFF Version for an m.2 slot?

>>60606309
>I plan to do lots of hashes.
you can probably find some asic- or fpga- based coprocessor for that.

>>60605883
pretty hard
afaik you can only get up to 100w from usb c which is barely enough over head for a 1050/1050ti

I was using a 750ti that I got for quite cheap a few years back. Total cost for me was the ~150 bucks (the GPU and the expresscard adapter) to slap onto the x230 I already owned. Because of the low power draw, I didn't need a PSU and I carved out a cheap enclosure I got from Radioshack for the GPU. I could easily fit the whole thing into my backpack with room to spare. Made Civ V and video editing more fun. No regrets. I imagine the same can be done with a 1050ti now.

they aren't really the same, you'd more likely require at least two separate sata power sorces connected to get enough power for a 6 pin pcie connection.

>>60608667

If the laptop has lesser res than the external screen, yes. But Thunderbolt's bottleneck will be larger as part of the bandwidth is spent sending the finished frame back.

Once PCIe 4.0 and thus Thunderbolt 4.0 are out this bottleneck will all but disappear, tho.

>>60606296

Because they are dumb fucks and poorfags is the only explanation I got. Thunderbolt over USB-C is literally the ultimate port and I can't fathom why anyone half knowledgeable about it would consider it a meme.

Heads up, Intel is releasing a royalty-free implementation of Thunderbolt 3 that will standardize eGPU, so in a year or two everything that supports Thunderbolt 3 will support eGPU enclosures.

>>60607130
what about thunderbolt 3?

>>60610605
its the same. they both use usb pd

>>60611646
fug. why can't cards not use such an ungodly amount of power?

>>60607196

Hopefully considering how cheap that thing was. I've seen them going for $140-$160 new. A lot more palatable than the $300 I spent for my Akitio Thunder 3 which I had to mod to even work right.

>>60611689
75 watts isnt too bad
You could possibly get away with 100 watts as the recommended overhead is at least 25% but I cant guarantee it exactly
Ive seen people run a 750ti with a 84 watt laptop charger though

>>60611831
i just wanted to try for a hackathon to run a gpu without a big enclosure and just a simple connector that goes from thunderbolt to pci+8pin. that way you don't need to plug it into anything but the laptop.

>>60611894
thatd be really cool though
say you could run 1030, which is give or take the same performance as a 750ti but come in at 30 watts which is more than enough to run on thunderbolt.
that said with performance drop plus the fact that you even have thunderbolt 3 (which means at least and 6 or 7th gen intel cpu) your igpu would come really close to what a 1030 can give you

>>60612891
is there anything more in the mid range for power draw and performance? like a 50w 1060?

>>60612953
nope
maybe if you really really under clock you could get a way with something but I doubt it

also I just noticed that I didnt mention this, to run a egpu on your internal you need a nvidia card and when you do run it over the internal display you also lose a bit of performance
which might be fine for calculation but for anything that needs real time rendering youre losing out on a few thing

>>60613050
why the performance drop from internal? because it's caching both from the igpu and egpu?

>>60613082
bandwidth and lane issues.
1. your display data and input back to your display is handled through the same connection which slightly eats up your bandwidth. This is a bit more intense on older connections like expresscard but its still there on thunderbolt
2. thunderbolt is handled through your mobo chipset so the lanes are shared between many other things like network etc etc
(I know /g/ hates ltt but https://youtu.be/FHwXOwTgYB0?t=6m50s if hes not talking out of his ass this isnt bad info)

also I know you didnt ask this but just in case youre curious, because amd was btfo during the era of switchable graphics amd never bothered with implementing proper internal display acceleration into their gpus while nvidia made optimus, which enabled them to have internal display acceleration

>>60602035
This, for me. I can afford a desktop (and in fact, I'm using one now) but when I start working overseas, I don't want to bring a massive gaming laptop with a video card that I can't upgrade. And since I do my gaming at home, I don't need to lug around a video card, adapter, and power supply.

Pic isn't mine but is very similar to my current setup.

>>60608667
Yes. You only need nVidia Optimus drivers (or Bumblebee if on Linux), it doesn't matter if it already has another GPU attached to Optimus so as long as you run your 970 with it (to my knowledge at least, I don't own any such laptops). Optimus also uses some sort of proprietary compression (but is only available on PCIe x1 2.0 rather than PCIe x2) which increases bandwidth also. Play with the settings, on my personal X220 it PCIe x1 + Optimus compression works the best, (surprisingly the CPU bottleneck isn't as bad as i thought) but YMMV.

>>60601999
Yes because Thinkpads support VT-d, but the performance will be very reduced because passing an nvidia card into a virtual machine (if running KVM) requires kvm=off which reduces CPU performance by a noticeable amount. AMD cards don't have the issue, it's an nvidia jewery thing.

>>60605984
I can afford a desktop, but if my Thinkpad or whatever business laptop I have in the future has the ability to just set up my regular battlestation with a dock and an eGPU that I can dock/undock willy nilly with no issues or required sleep/reboot cycles to initialize it, it'd be ideal for me. It does intice poorfags because it lets you use a GPU without buying a desktop, but for me it'd be awesome to be able to have 1 machine that I can pick up and take with me somewhere to use on the go for light stuff like browsing, taking notes, working with cameras, etc and then come home and set it on the dock and have all that performance immediately available but on the same machine I was just using 2 hours ago at a business meeting. It'd be really convenient. I'm happy with my Thinkpad + desktop situation at the moment but if this becomes a thing in the future as hardware becomes more power efficient and Thunderbolt becomes more widely used, I will gladly switch over as long as the laptop is sturdy.

Are there benchmarks for external vs internal, especially against various connectors?

It's slightly less a meme than it was years ago, it actually is becoming a viable thing now.

>>60602008
I would like to use such a setup so that I have a portable base laptop (i.e. containing all programs and data in a secured state) while being able to dock (monitor, keyboard, mouse, gpu) and do gpgpu stuff instead of getting a dedicated workstation for it.

>>60602018
The closest thing to that is somehow finding a MxM Laptop less than 400 and upgrading it's existing GPU. Even so, Eurocom doesn't seem to be offering any 10xx upgrades for non-Eurocom Laptops atm.

I also have a 500W power supply and all the necessary cables. My problem is with drivers. My laptop has integrated Intel graphics, as well as a dedicated nvidia card. I disable the nvidia card from device manager manually and try to install the driver for my card (which is a 1060) from nvidia's website.

Whenever I try to install it, it simply enables my dedicated video card again and doesn't install the driver for my 1060.

You may need to limit the clocks to get some headroom. That or get a messier USFF/BTX power supply rather than the power brick. Definitely doable though the GTX770 will probably choke if you're using PCIe x1 and/or ExpressCard.

Seems like a waste of money, a thunderbolt 3 GPU enclosure will run you 300-400, a decent card will run you another 300.

You could just buy a laptop with a 1070 in it at that point.
