My HD 4850: 512mb vs. 1gb (results)

post #1 of 18
Thread Starter 
First, I'd like to introduce my new baby.


Model-specific specs
Model: GV-R485MC-1GH
Stock clocks: 625mhz core, 1920mhz mem
Memory size: 1gb
Cooling: Gigabyte's Multi-Coreâ„¢ Cooling Technology


The box hasn't changed, but to include mention of the upgraded heatsink on this card.




As we all know, the reference cooler on all of the original HD 4850's was poorly suited for overclocking.
This massive heatpipe cooler is the reason I asked for this card. It's meant to be passive,
so the heatsink is bigger, with much more surface area/plenty of fins.
Think what this passive cooler could do with a little airflow.
The only obvious issue is the lack of memory and pwm cooling.
As well as with Gigabyte's other GPU heatsink, there's little room for memory cooling.
I rarely use ram sinks, but when I'm dumping on the clocks, I usually have a high-cfm
fan throwing enough air across the chips to keep them cool. I'm not adding pwm sinks
for the shootout since it didn't come that way, but I will be for serious benching later.
Plus, looking at the pwm layout on this card, I'll end up cutting a heatsink down to custom sizes for them.
I'll add some pictures when I get them on.







The back. Everything's been moved around! That means no volt mod out
of the box like I was planning. It'll come soon enough though.





Sitting in a Gigabyte EP45-UD3P (still reviewing the board). They match perfectly.





To briefly test the cooler out, I set the core clock to 750mhz, and ran 3DMark 03
(the first 4 tests) and left rivatuner open to monitor core temps.
I hovered the mouse where the temps were the highest for the screenshot.
In case you can't tell, the one on the left is with no fan, the one on the right
is with a low-cfm 80mm fan resting against the heatsink. I haven't tested
for max clocks yet, but will add them to this post when I do.
Card clocks top out at 780/1200 on stock voltage, which is better than the 512mb did.

The cards

Both of these are Gigabyte.




Testing configuration
CPU: Intel e8600 @ 4.5ghz (8.5 x 530)
Mobo: Gigabyte EP45T-Extreme
RAM: OCZ Platinum DDR3 @ 707mhz, 5-5-5-15 2T
CPU Cooling: TR Ultra-120 Original
GPU Cooling for 512mb: AC Accelero S1
GPU Cooling for 1gb: Gigabyte Multi-Core Cooling
PSU: Gigabyte ODIN Pro 1200w
HDD: 36gb WD Raptor
Card clocks will be 640/1000 for the first round of testing, then 740/1170 for the second round.


To obtain a comparison as accurate as possible, I'm using very specific and identical settings and testing methods.
Core and mem clocks on both cards will be identical to each other. I'll be doing testing at close to stock, and at overclocked speeds.
Each card will have a brand new OS install, and all software and drivers installed identically, even in the same order.

While the 1gb only pulled WAY ahead in one bench, it did feel smoother while actually playing games. The big problem I have with that, is it's too perceptual. I could have just been expecting that, therefore experienced it that way. I would probably have noticed a bigger difference if I did any regular PC gaming

That is a really nice stock cooler...

Non reference design 4850 have more voltage on the core then normal 4850. I think its around same volts as 4870.

So basically You don't need to spend extra $ to get 1GB? BTW my super clocked 4850 get 48fps Crysis High 1680*1050 DX9
