Why No 10GbE For Home Users?

But it will still be decades before it gets implemented and to mention that homes still prefer ethernet and wifi rather than fiber optics and SFP.

When cpu's get fibre optic connections (soonish), even 'homes' will prefer that over Ethernet. :)

You mean laptop and desktop motherboards? The CPU itself doesnt have ethernet and network cpus like Tilera TIleGx have pipes to the CPU.

Even desktop CPUs arent fast enough to support many Tb/s of networking, you will need a cluster of Tiles/cisco datacenter blade routers (like they use in internet exchange) or even GPUs. From the tests of the GPU based linux router 2 GTX 480 were able to perform 100Gb/s. So If recent GPUs are 10x faster they could probably do 1Tb/s if their memory bandwidth is fast enough.

Router Chipsets are odd-ducks for folks that are used to desktops, etc...

The real horsepower in a router chipset is not the CPU, but the switching fabric underneath - the CPU just provides the control logic for the switching matrix - which always begs the question - why Tilera? How many of those cores are actually used to move traffic around?

It takes barely any computing power of a single TileGx core to move traffic around in the best home internet in the UK. Thats how embarrassingly slow internet in the UK is.

For desktops, the CPU is important in throughput as something has got to process the data that goes into packets.

From testing all the cores can be used to move traffic around. The TileGX is like a switch fabric except that it uses general purpose CPUs in a mesh grid so it is less power efficient than a switch but gives you the flexibility like as if you were using an x86 CPU.

Actually - the Tilera itself, at least in the RouterBoards, has little to do with the data plane performance, it's mostly the switch chips.

It's an interesting chip - I have an engineering sample now in hand - but for Routing, it's not a great net-add than another other chipset - the RouterOS is a more significant factor here, as well as the switch chip in use - it's all software, just like any other router on the control plane, so it's really down to how fast, and how many streams the switch itself can handle perhaps.

I know data plane doesnt do a thing, im just saying in a standard switch chip it has many tiny cores that only switch things around. The Tilera is like that except that it uses general purpose CPU cores instead.
 
Which also inherently negates your statement on the other thread - it's SW based, not HW...
if you mean the thread asking about pfsense i said its all software based and what the OP meant was embedded.

If you mean how the Tilera works in general it has less overhead because the network interface stuff or pipes are part of the CPU so there are traffic goes through less stuff before and after the CPU. The TileGx is essentially a network optimised version of the TILE.

I wouldnt call the Tilera inefficient in processing, its just less power efficient than a switch for switching (bridging as it uses software) but it can do routing that a switch cant. So its more compute efficient than using a general x86 or even ARM in networking but less power efficient than a switch though it uses the same amount of power as x86 but able to route more than x86 for the same amount of electricity. The tilera has dedicated float units just like with the encryption units but mikrotik doesnt make use of it so while the Tilera TileGx is comparable to x86 in math performance, mikrotik doesnt take advantage of that. Its a bit like not taking advantage of SSE.

Since you have the engineering sample you have quite a lot of freedom in that you could even attach a GPU to it as it does have PCIe in configuration of x8,x2,x2 (or x1,x1) allowing for a total of 3 slots. It does share some similarities with modern x86 such as the integrated memory controller and integrated PCIe controller but has a lot more integrated NICs/pipes. Im not exactly sure if there is a chip between the NICs and CPU or if it is just direct though on the board.
 
I'm pretty disappointed that 10g has just sat around since 2003.

It's awesome that the cable doesn't have any crosstalk and eliminates the need for dsp correction.
