Hi,

Just purchased a AMD Radeon 4850 1 GB GPU to replace the Radeon 4850 512 MB card, mostly because the 1 GB card has exhaust - the 512 MB card does not exhaust & it runs hot. In fact the entire PC (XPS 435MT - Dell) runs hot in my opinion because of the 512 MB GPU.


The WEI Subscore for the Graphics & Gaming Graphics was 6.0.


Don't remember when my last WEI assessment was run - so decided to rerun & the Subscore for the Graphics & Gaming Graphics went up to 7.3 !!

That seems like a pretty significant jump.

I have not yet installed the new card - this is still the old 512 MB Radeon.


The only things I may have changed since last running the WEI assessment are - added a Dell2412M as a second monitor (the primary monitor being a 3007WFP-HC). Previously the second monitor had been a Dell E196FP.

And I changed the screen resolution to 1440 X 900 on both. Previously I had the screen resolution set @ 1920 X 1200 on the 3007 - & on the E1906FP the resolution had been set @ 1280 X 1024.




Any ideas why my WEI is better?

Well first 128 vs 256 to put it simply the 256 has twice the memory bandwidthing meaning it can handle more data at once. That tends to be important when your gaming at @1080p or higher with heavy of "aftereffects" like AA etc. So basically any mid to high-end card should be at 256 or better nowadays.

Now new cards have been improving power just like CPU's so say a 7850 model which is probably twice as fast as your 4850 but uses less power do to a better design.

my question is why did you buy a 4850 card in the first place ? I would think you could find a at least a 5850/6850 on the cheap. Also looking at your specs you have a pretty good PC I think even a 7750 would be better than the 4850 if only for power use and direct11 support.

Supposedly (per Dell forum) the Radeon HD5770 is the fastest card that can be powered by the stock 360x power supply that ships with the XPS 435MT. Browsing the Dell forum you will find a number of threads detailing great difficulty installing higher wattage PSU. Not much room in the cabinet. Never much cared for gaming just wanted a PC that wouldn't be antiquated in a few years.

Remember now that when I installed Win 7 in 2010 all the WEI numbers were in the sevens except for hard disk. Guess my question should have been - why did my WEI go down to 6.0? Hope the numbers posted above mean the XPS will be sufficient for some time yet. Want to get as many years as possible out of this PC. It is whisper quiet.

Have been very happy with this card so far & since I live in a cold part of the USA the only time heat has been an issue is July & August - no A/C.

thanks

Hi thanks for responding,

A few times a year I get interested in how my PC works & ask a few questions so bear with me:

Some years ago I remember reading a thread regarding an upgrade to a better card that did not have a 256-bit memory interface & the poster was disappointed. Like the graphics on his 4850 better. While looking @ newer cards I notice a lot of them are 128-bit. Can you tell me how important the 256-bit vs. 128-bit memory interface is?
Purely for the sake of knowledge as I already purchased the 1 GB version of the 4850 am certainly going to stick with it.

Also if the newer cards use less power I wonder why the Dell Forum Thread said the 360 watt power supply in the XPS would not support any GPU higher than the 5770? Tho that post is 3 year old now.

thanks
