Samsung Touts 4GHz Memory for Graphics Cards

Samsung Touts 4 GHz Memory for Graphics Cards

Getting more speed is always nice - and Samsung is about to break the speed barrier yet again, pushing GDDR4 chips to 4 GHz and beyond. At the International Solid-State Circuits Conference (ISSCC), Samsung presented its new GDDR4 memory chips that operate at about 40% higher speed than GDDR4 was initially estimated to, but use more power.

4 GHz GDDR4 memory chips are only "available" in 512 MB capacities and were manufactured using 80 nm process technology. They were designed for a power supply voltage of 1.4 V – 2.1 V, reports PC Watch web-site. The data rate of 4 Gb/s (4 gigabit per second, or 4 GHz) was achieved with devices operating at 2.0 V, which is higher than Samsung’s current-generation GDDR4 chips that can function at up to 1.9 V officially.

GDDR4 memory at 4.0 GHz delivers bandwidth of 16 GB/s and if such chips were used in today’s graphics cards that have 256-bit memory bus, this would result in peak data bandwidth of 128 GB/s, two times more than the ATI Radeon X1950 XTX (the only graphics card on the market that uses GDDR4) can offer. For tomorrow’s graphics boards that will have 512-bit memory access Samsung’s new chips would give peak memory bandwidth of 256 GB/s, which is nearly three times more than 86.4 GB/s that the currently highest-performance graphics card – NVIDIA GeForce 8800 GTX – has.

Are we beginning to enter the era when GPU memory will be clocked many times higher than our CPUs?Source: X-bit Labs and PC Watch

So is this 2Ghz DDR (4Ghz)

That would be niceeeeee..

1./ X1950XTX bandwidth 64MB/s
2./ 4GHz GDDR bandwidth 128MB/s

Therefore
  • The new memory has twice the bandwidth, or
  • The new memory has 100% more bandwidth
(not "two times more"... which would mean 192MB/s)

lol calm down take a breath :p hehe jk

yep 1ghz+100% = 2ghz (ddr 4ghz)

though im bettin there are many significant trimming differences between the 2 chips in question therefore probably not a true 100% increase (could be less or maybe even more) we are just discussing theoretics here :)

Could the R600 have been waiting on these chips for the GDDR4 models? This is awesome and I Cant wait for this to happen. Now, if only these were true for Memory Modules for the system (eg. DDR300)

Wow this will offer some incredible gaming performance. Woot Woot I see teraflop gddr memory performance in the somewhat near future lol :rockout: edit: oops I did'nt notice the double post. The difference is the rock-out headbanger icon shows that I am very excited about this indeed hehe.

Spot the difference lol, you might win a prize :laugh:

Lets see how it actually performs. It would be nice to shove it onto a card that has GDDR4 already and see if there is any measurable increase.

how is 128 not double of 64?

he is talking in percents lol (2 times+original amount =192 :))

the article is talking in referances to current video cards...2x as fast is speed times 2... if it were percents there would be % in there. two times the speed or 2x the bandwidth is the bandwith times 2, or 100% faster.

EITHER WAY this stuff is twice the speed of what we have now. percentage comparisons suck anyway.

Nvidia is so screwed... ATI/AMD are basically gulping down all the GDDR4 that is availiable LOL
