Closer Look:

The line of 5750s pack in 720 stream processors - 80 fewer than the RV770 and the full Juniper core of the 5770s. The 5700s use a 128-bit memory bus while the prior RV700 used 256-bit, the smaller bus allows for a simpler and cheaper design at the cost of bandwidth. The smaller fabrication process allows for smaller dies that use less energy but still have the same number of stream processors as the prior generation - each GPU core costs less than its predecessor and is more efficient. Both the 5750 and 5770 target the midrange market segment, and just as the 5870s and 5850s can be ran in mixed CrossFireX, so can the 5770 and 5750. 1GB GDDR5 is the norm for 5-series cards so far, but vendors have the option to opt for 512MB memory on the 5750 - the one from PowerColor packs 1GB. The card is said to use approximately 16W when idling and around 86W at full load, so the PCI Express 6-pin connection is needed. Just like the rest of the 5-series cards, this one supports DirectX 11 - titles are finally trickling out that support the new standard. One thing to mention is that both the PCS+ 5770 and this 5750 have nearly identical layouts except for minor differences in the heatsink, video out options (the solder points are there for both), and some left out power circuitry. The 5750 has a bright red PCB with a semi-transparent smoky gray shroud/fan attachment clipped on to an aluminum heatsink. The memory isn't cooled, only the GPU core. The standard two-slot CrossFireX ports are still available, and no back plate is used as is common on higher end ATI cards.













The memory is made by Samsung with the code K4G10325FE-HC04, very common with 5-series cards so far. The memory is rated for 1250MHz and we will see how well it achieves that when it is clocked in at 1150MHz. The memory is intended for 1.5V but I cannot verify at this time since I do not have my voltmeter with me to see what it's running at on the 5750. Samsung has a data sheet readily available on the web for anyone interested in what the code means but it simply translates into 1GB 1.5V Samsung memory. Looking at the card from the side it is obvious that the heatsink is only intended for the GPU core, and the fan results in it taking up two slots. The fan shroud clips onto the sides.



The top side of the heatsink has slits gouged into it - probably to help heat dissipate from the memory ICs. The fan does not use a sensing wire so there are only two wires for power. The heatsink was cut so that it could fit over the small capacitors and chokes. Power comes through to the back of the graphics card as is typical with most ATI cards. This card has HDMI, DVI, and VGA outputs - it has room on the PCB for the double-stack DVI port but PowerColor opted for this configuration instead and were able to use a single expansion bracket rather than two, as is common with most of the 5-series cards.



Let's get the drivers installed so that we can test it already!
