Hi guys!

 

 I want to buy a gigabyte  gt 630  2 gb  128  bits,  but it seems there a difference  between rev 1 and rev 3.

 The clock is  at 810 mhz  at  rev 1 and  700  at rev 3

 I would  choose the rev 1 , if i could  find out whats the transfer rate of it is, but  till now  could  find only those details for the rev 3 only

 

 

  Thanks  for the help,

 

 Jules

For info, the two side by side :- http://www.gigabyte.com/products/comparison/list.aspx?ck=3&pids=4751,4217

 

What transfer rate are you referring to?  Theoretical memory transfer rates will be the same - because the memory runs at the same speed (1600mhz) and has the same bus width (128 bits).

You do realize this card is worthless for gaming right?

I meant  the memory bandwith.I  know that at rev.3 its  25.6GB/sec , but  could not  find any details  about rev.1 on this aspect

The memory bandwidth will be exactly the same.  It's calculated as (Effective Memory Speed x Bus Width)/8.  These numbers are theoretical rather than benchmark proven, but I think all manufacturers do the same thing.

 

So (1600mhz x 128bit) = 204800

204800 / 8 = 25600 MBps or 25.6 GBps

 

 

The GT630 is not great in the price/performance stakes, and really is only a modest performance upgrade from a HD4670.  By this I mean although it's cheap to buy, the performance you are buying per $ is not great.  A little up the price range is where manufacturers really compete.  For example, a GTX 750 (non Ti) has a street price starting from about $100-$110 in the US compared to (I'm guessing) $60-70 for a Gigabyte GT 630.  However, with no exaggeration, the GTX 750 performs approximately 4 x faster overall than the GT 630. AMD's R7 260X is not far behind, and in a similar price bracket to the GTX 750. Personally I would try to find the extra $40 for 4 x the performance, even if it meant holding off for a month or two.

 

If the extra cost is just not an option then there are deals like this R7 260X at $70 (however part of that price is made up of a mail in rebate). For a clean price with no mail in rebates etc as close to the price of the GT 630 as possible, there's (for example) this GT 640 but there aren't many options at this price level.  It's not in the same league as the GTX 750 or R7 260X by a long way.  But it does at least feature GDDR5 memory and overclocked GPU and should perform better than the GT 630 DDR3 by about 50%. A 'trick' at the low end of the GPU market is to offer models hampered with slower memory (DDR2 or DDR3) at cheap prices while the samples sent out initially to review sites get fast GDDR5...  Always check what memory is used in any prospective purchase and if DDR3, look to see if a GDDR5 version is available for similar money.  GPU's really benefit from higher memory bandwidth..

what about http://www.game-debate.com/hardware/?gid=2118&graphics=Radeon%20R7%20240%20MSI%202GB%20DDR3%20OC%20Edition?

 will it perform better  as  the gt630 and is it compatible  with the  system mentioned above?

Bit better, not a lot :)  - http://www.tomshardware.co.uk/radeon-r7-240-and-250,review-32874-7.html (bear in mind all tests are at lowest quality settings in that review).

 

It's a low power draw card.  There's no compatibility issues as far as I am aware.

how  about this?

http://www.game-debate.com/hardware/?gid=1050&graphics=GeForce%20GT%20640%20Zotac%202GB%20Edition

but  at the one i m looking its added low profile bracket also--

Zotac GeForce GT 640 2GB DDR3 128-bit low profile bracket

what that means?  something  its underclocked?

also  it seems  this  zotac  its with PCI Express 3.0 x16  but my  mobo has  pcie-2.0  only..is that an issue?

The site you're linking to has a compare option with a commentary.

 

R7-240 2Gb DDR3 vs Zotac Geforce GT 640 2 Gb DDR3 - GT 640 wins vs R7-240.

Zotac Geforce GT 640 2 Gb DDR3 vs Geforce GTX 750 1 Gb GDDR5 - But can't compete here..

 

Low profile bracket means it's a half height card that will fit in a slim HTPC style case.

 

PCI Express 3.0 cards are backward compatible with older standards, so that is not a problem.

so its  smaller..does  that means  fits better  in a minitower but harder  to install in a midi case?

No, it will fit in either type just as easily.  Probably it's pre-fitted with a full size bracket with a half height one in the box for use on slim PC's.
