Razer blade 15

[eltharynd]

Hello,

 

So i just ordered a razer blade 15 advanced full spec with 4k oled display.

 

I was browsing specs cause I can't wait for it to arrive.

 

I noticed on razer's page they specify it's got a Mobile Intel^® HM370 Chipset.

Browsing at intel's chipset page it sais:

• PCI Express Configurations ^‡x1, x2, x4
• Max # of PCI Express Lanes16

and that got me thinking...

Does that mean there will be maximum 4 lanes running the rtx 2080? and if not, does that mean that if it's using 16 lanes nothing else will have available lanes?

I'm quite rusty on how PCIe bus works, anyone got more clarifications?

 

It looks right now as the amount fo data i will be able to send to the GPU will be a huge limitation on such a GPU??

I'll mostly use it for machine learning tbh so the faster i can send / process / receive data the best.

 

Thanks

CPU Lanes and Chipset Lanes are different, you have 16x from the CPU for the GPU and then all the rest is Chipset based for stuff like NVMe.

Wait i Might have the answer myself..

 

Max-Q has significantly reduced base clock, so does that mean they always use 4 lanes cause it won't be able to process more than that data anyway? I'm guessing that's my answer.. anybody can confirm?

but... isn't the CPU bus "forwarded" through the mobo lanes? and are mobo lanes the same as the chipset lanes? that's how i always imagined it

The "lane traces" obviously are all embedded onto the motherboard, but you have 16x pci-e lanes that go straight from the CPU to a specific pci-e connection, on this laptop case it connects to the RTX 2080 and that's it.

 

Then you have the PCI-e lanes that comes from the Chipset and connects to the other expansion devices.

 

Basically you have CPU PCI-e Lanes and Chipset PCI-e Lanes, both uses the motherboard traces but they are separated from one another.

Ok. thanks for clarifying
