Upgrade G4 to G5 processor!

Post by **hubird** » Mon Sep 29, 2003 4:49 pm

Got this text emailed from a friend, it seems to be not really new news, however I didn't know it.
(Google for New Gigacelleration Alien World Technologies, and find some links).

New Gigacelleration Alien World Technologies this morning announced the first G5 processor upgrade for AGP Power Macs. The dual 2.0 GHz PowerPC 970 promises the same level of performance as Apple's Power Mac G5 at half the price .

Designed to plug into the ZIF socket of Power Mac G4 models with AGP video, the Hermes Xtreme Dual 2.0 includes two bleeding edge G5 processors, each processor has the same 64K instruction cache, 32K data cache, and 512K onboard level 2 cache as the processors used in Apple's soon-to-be-released powerhouses.

The Hermes upgrade will also have something no Power Mac G5 does -- a high speed level 3 cache , something not mentioned once in the literature IBM has produced about the PPC 970. Why not? Because it isn't designed to work with a level 3 cache. (IBM instead designed it to work with memory that has a very fast front side bus.)

New Gig teamed up with engineers at IBM to produce a 16 MB static RAM level 3 cache and a cache controller to manage data transfers between the 100-167 MHz bus of the Power Mac G4 motherboards and the 2.0 GHz G5's requirement for 128-bit 1.0 GHz memory.

Despite the huge expense of designing this hardware, New Gig president Lots O'Speed expects to "sell a million of 'em," so the multimillion dollar technology investment will be spread over at least one million Hermes Xtreme cards. (If New Gig can't sell a million, they will be forced into bankruptcy, which has been the fate of too many other Mac accelerator makers.)

By interleaving two 8 MB banks of 512 MHz static RAM , the PPC 970 functions just as it does in the Power Mac G5s. Better yet, the ultra fast RAM New Gig uses means a lot less delay when the G5 processor accesses data in the L3 cache.

Unfortunately, cache misses will carry a huge performance penalty, since the L3 cache is 3-5 times as fast as the system bus. Chief hardware engineer R. U. Gullible comments, "Them's the breaks."

The breakthrough processor upgrade design includes a four fan cooling system for the CPUs and runs ducts to one of the Power Mac's PCI slot openings to move cooler outside air over the processors.

New Gig anticipates shipment for mid-September with a projected retail price of $1,499 -- just half what the top-end dual 2.0 GHz Power Mac G5 sells for.

For those on a budget, New Gig will be offering three other configuration:
Hermes Extreme Mono 2.0, a single processor version
Hermes Extreme Dual 1.6 with two 1.6 GHz CPUs and 4 MB of L3 cache
Hermes Extreme Mono 1.6, a single processor version

New Gig hopes to sell the Mono 1.6 for $799, the Dual 1.6 for $1,099, and the Mono 2.0 for $999. These should all be available sometime between mid-August and mid-September.

Nobody at Apple or IBM was willing to be quoted in print, but one Apple engineer was heard to comment, "New Giga what?!?!?"

Is this for real? If so then it could solve the PCI thing in a snap. My AGP G4 would love to be a G5 with PCI slots and OSX

Considering it came from Anne Onymous ("anonymous" in english) the President of the company is Lots O' Speed and the Chief Engineer is R. U. Gullible (look up "gullible" in your nearest english dictionary) I would say this rates about a 110 on my crap-o-meter.

We don't even need to go on to practical considerations like "What chance in hell would Apple let these processors loose on the upgrade market to compete with themselves?"

guess you're right

Let's better wait for compannies like GigaDesigns, Sonnet or similar sell such upgrades. Those SANY, Panasonix or other like compannies scare me

Meanwhile we can consider other things like G4/1.4GHz upgrade cards. They are very reliable these days (no drivers, you put them instead of your processor, system 'sees' them as standard processors, they feature L3 cache so even if your machine has 100MHz bus they act like those 133MHz). Isn't it enough for a while?

That'll teach me not to read the whole post - i didn't even see that Lots O'Speed character.

except this upgrade will NEED the level 3 cache because the G5 apples actually have a very fast FSB and memory bus, otherwise you would be stuck interfacing directly with g4 pc 133 memory bus
