| I was reading about the new memory cards started by Sony, Lexar and Sandisk.
They use a PCIe interface. If the Natami team were to upgrade the Natami, this is fast and it would look like a good choice. The downside is that it would require a license to sell it. $130 for 16 GB cards and $230 for 32 GB cards right now but it will drop.
Regular SD cards probably max out at 45 MBS unless you have one of those Lexar cards.

| The hurdle is getting a cheap enough main FPGA that can handle PCIexpress and SATA. Within a few years, it might be affordable enough. But right now we are talking about a ca $2500-per-board scenario if building such a system.

| Andre your being optimistic, it's more expensive then that you would be safer to say between 2500 and 3000 per board.

| How many people here or in the Amiga community would pay for a Natami super computer? If they made one for under $5 or $10,000, how many would be interested?

| @Chuck T I would be interested... the same way I was intersted in the Amiga A4000 towers by QuikPak... Unfortunately for what I needed/wanted it to do, it was way out of the price range I could afford. At the $5k to $10k price range we would have to have a Market segment that needed such a machine... no reason to even think of designing a machine without a "growing" Market Segment to serve. Are You familiar with SGI and the Indy designs they produced in the Mid 1990's? If you can look at the prices they were selling for between 1994 & 1996... and they had steady competition from Sun & Dec let alone HP for their market segment... That's why it still made sense for Produce Amiga 4000T's for the Video segment at that time... a full Flyer system was still a bargain at the $9k to $10k price range.

| Well, the Achronix Speedster HD series has 24 lanes of PCI-Express 3.0 builtthrough hard IP, and if the SerDes numbers are to be believed, it can generate up to 156 more lanes too. I realize that all these decisions were made long ago, but if I were to be placed as head of a hypothetical Natami II/Son of Natami project, I would use one Achronix Speedster 22iHP560 for a perspective 7-way 68070 core and 96000 DSP and one Speedster HD1500 for the chipset. The only problem I have with them (and it's admittedly pretty pretty nitpcky) is that they only have memory controllers for DDR2/3. I would have loved to have had a memory controller for RLD3.

| Ben RLDRAM is simply too small for something you compare similar DDR2 modules we accept the latency for what it returns more memory on a single die! The closer you place memory to the FPGA the lower the latency, However you might get interference from the FPGA if the power planes are not lay out correctly, besides that the number of Planes on the PCB increases exponential to elevate such problems.
