hardware OS4   hardware OS4 : Troika Amy Design-speed Upgrades
   posted by Troika on 12-Sep-2006 9:08:19 (17368 reads)
Amy'05 update part 1
Speed & upgrades

This is the first of two updates on the Project Prometheus/Amy'05 design that we will be releasing this week. The second part before BB4, is scheduled for Wednesday 13th September 2006.

Read more for details... (mod note)




The PowerPC CPU has been improved upon, we now have an IBM 750GL @ 800 MHz with 1 MByte of L2 cache, against the previous 512K of cache. The design of the motherboard will support 750GL CPUs upto 1 GHz core speed in the future. The 800 MHz part was chosen as the baseline as it represents the best price/performance mix.

To keep the system cool, both the CPU and our Northbridge the Tundra TSI107 need heatsinks, but the TSI-107 does not require a fan in normal use. The Troika team developed a thermostatically controlled fan system for the CPU and optional case fan. Amy has a dedicated fan controller IC, this will allow quiet operation, if allowable by system usage patterns.

SDRAM DIMM detection has been improved compared to previous OS4 capable systems. The TSI107 provides the necessary features to more accurately setup the SDRAM timing based upon the Serial Presence Detect (SPD) ROM parameters of the installed memory stick(s). This will ease the purchasing of suitable RAM for Amy'05.

In keeping with the speed increase, the graphics slot has been doubled in speed. The PCI slot for the graphics adaptor now runs at 66 MHz, yielding a maximum throughput of 264 MByte/sec. This provides comparable speed to the AGP 1X slot.

From previous experience, this bus speed has been sufficient to run 1280x1024 Open GL 2D/3D graphics @ 60 Hz with no issues using the ATI Radeon 9700 series and above graphics cards.

Only one PCI slot supports the 66 MHz speed and there is the appropriate bridge chip and logic to connect to the system 33 MHz PCI bus.



That is all for this update, the second and final update is on Wednesday.

If you want AGP or DDR, yu don't want the "budget" (relatively speaking) board.


Relatively speaking, Articia S northbridge was cheaper than Marvell Discovery II, yet products based on latter were cheaper and users didnt have to hunt for rare and expensive SDRAM. How much you save in the end?

No.

I bought it to make up an order to get free delivery.

The Firewire card was on £13

MAI may have given a discount to get their market started because they were new and unknown (Even the Freescale people I talked to at FTF a year ago didn't know who MAI was or what Articia was, and they created reference design boards for Marvell and Tundra northbridges). Maybe they discounted because of the bugs. Maybe no one was interested at their original price goal and they were forced to reduce it to get even only Eyetech/Genesi to buy. Who knows.

I had no idea they were cheaper, and I'm a bit suprised by that. I'll do a Helgis - I reject your reality and substitute my own. *

At the time I bought mine, SDRAM wasn't rare, and was less expensive than DDR. SDRAM was on its way out, for sure, but had not yet reached the status of being eccentric and thus more expensive than its successors, as it is today.

(40% speed increase from an AmigaOne–SE 600 MHz)
+ You get working USB ports

How about if I come for a visit to Hungary? Can I geta free beer? What ones would you recomend?

I'm not too worried about the current specs for the Amy'05. It looks great! I plan on putting my BBS on my new Amiga. Then I will gladly get another one for my day to day stuff and keep the Linux/Windows box around for other things, such as...well.... um...... Lemme get back to you on that.

How about they just give us a PCI-Express slot and let each of us decide if we want to spend US$250 on that thing to plug into it? Neat idea, too bad it sounds like a Mac product (No Windows/Linux drivers mentioned). Might we even be able to get drivers ported?

@NutsAboutAmiga

Not only that, you'll get USB2.0, Sil680 and maybe even Gbit ethernet.
Too bad that they didn't convert the 66MHz to a AGP slot though.
Would have been the perfect desktop beginners board then.


@Itix

Tundra 107 doesn't support DDR so there's nothing they can do about that.
Btw SDRAM is not hard to get. Every computer internet shop I searched in had those.
Granted they're more expensive.


@Troika

Hope to see PATA+SATA, G4, DDR2, PCIe on your next board?

Radeon X1300 256MB PCI newly released even.

What about 2D support for this Forefront?
3D Hyperion?

And I'd bet Pixel32 will not work in usable form on AmigaOS4 until that date.

I wouldn't say its too expensive. A quick look on ebay shows 512MB PC133, buy it now, from about £25, that a 1/4 of what i paid to eyetech for the RAM I have in my XE. Second user ram is going for about £15-£20 for 512MB

--typo--

Anyway way not use the TSI108 or TSI109 chip?

TSI109 supports dual CPU’s

I think Troika convert the 66 Mhz to AGP Slot.
Look here:

Yes it’s where nice that configure one the 66 mhz PCI slot as fake AGP.

My understanding is that it’s getting hard to find a PCI graphics card in your local PC shop.

@ironfist

Yes but you pop up in every thread attacking OS4 and potential new hardware, promoting Peg and MOS. You can do this, but it is getting boring.... months after months....

You're referring to other highend Troika project not to Amy05.

@all
Am I the only one who wishes that Troika would STOP improving their mobo, and just release the damn thing? Does no-one remember Mick Tinker & the Boxer?

And IMHO, who-ever releases a board first, even if it is lower spec, is going to get the majority of the sales (assuming they can meet demand). People are fed-up of waiting.

A word of warning. Way back when I was testing RAM sticks on my A1XE running the very first beta versions of OS4 I discovered some RAM manufacturers used false SPD specs to work around PC memory controller bugs. I don't know if this practice is still common but consumers should not be surprised to find some memory sticks just won't work or don't work as specified. Buyer beware.

@Troika
Great work on the Amy guys. Now please ignore any and all requests for changes to the design and ship it. I keep having this nightmare where a beta Amy board attacks me but every night it is a different revision. I had the same nightmares when the BoXeR project was going on.

We'll have to see how much crunching power Amy has in terms of compiling large C++ projects. I look forward to setting up the experiment and comparing between the A1XE and MicroA1-C models.
