Continuing off of the review of the PowerColor PCS+ 5770, I have received a PowerColor 5750. The 5750 packs less punch than the 5770, with a lower clock rate and fewer stream processing units – 720 rather than 800. Both are built on the same 40nm fabrication/Juniper core and are virtually the same except that the 80 stream processors (one SIMD) are physically disabled. Both feature 1GB of GDDR5 - 1GB memory is becoming very common in the mainstream finally but the 5750 can also be had with 512MB memory. Another similarity is the PCB – they are close to the same with some minor differences on which video outputs were installed from the factory, and some of the power regulation circuitry was left out since this card uses less energy – one PCI-E 6-pin connection is still left on the board for auxiliary power aside from the PCI-E port. As typical of all of the 5-series ATI/AMD graphics cards, this card supports DirectX 11 and ATI Eyefinity. This card can also be run in CrossFireX with other 5750s and 5770s. The stock clocks match the factory reference clock speeds of 700MHz and 1150MHz on core and memory, respectively, on a 128-bit memory bus.
The benchmarks will reveal how big of a difference the disabled SIMD unit and lowered clocks affect the Juniper core. It will be compelling to overclock the 5750 and see how well it clocks in comparison to the PowerColor PCS+ 5770.
A warrior that resembles some characters out of the Dynasty Warriors series and headed by “Unleash the gaming power,” adorns the front of the box along with the terms 1GB GDDR5, DVI HDMI, and PowerColor Radeon HD 5750, while lightning bolts touch down along with a dark building that sits in the background. The back of the box has some specifications and features in seven languages - the box lists some of the general features of the card: ATI Radeon HD 5750 with 128-bit memory bus, PCI Express 2.1 support, 40nm fabrication process technology, DirectX 11 / Shader Model 5.0 Support, ATI Stream technology, ATI CrossFireX multi-GPU support for highly scalable performance, ATI Avivo HD video and display technology, Enhanced Unified Video Decoder 2 (UVD2) for Blu-Ray and HD content, and built-in HDMI with 7.1 surround sound. Some of the features are then highlighted and explained somewhat. Centered at the bottom is a box with stars in it to rank what the graphics card is best put to use for - it is given four out of five for gaming, and five out of five for video and office usage.
The first side explains the power and system requirements for some of the supported technologies. Simply put, a motherboard with an open PCI Express x16 slot is needed, a 450+ Watt power supply with at least one 6-pin PCI Express connection and 600+ Watts with two connectors for ATI CrossFireX. 1GB of system memory is suggested and to play DVDs and Blu-Ray discs users will need DVD and Blu-Ray drives. To run CrossFireX users will need to have two video cards, two PCI Express slots, and a CrossFireX ribbon cable. The top and bottom of the box both say PowerColor - overall a nice, clean box.
Opening the box there is a typical cardboard box held within, with folded tabs enclosed around the accessories and graphics card. Prying the box open - the card is protected by an antistatic bag as is typical with sensitive electronics. Here is the first glimpse at the new video card up for review.
The accessory pack is quite spartan in that it is really basic - a guide and a driver disc. No Molex to 6-pin adapter, and since almost everyone will be able to hook up to the video output no adapters are included.
Let's move on to the 5750 itself!
