The Radeon HD 5700 series, codenamed Juniper, has long been rumoured to be a Cypress cut in half – 800 SP / 40 TMU / 16 ROP / 128-bit bandwidth. However, recent rumours point to 14 SIMD clusters instead of 10 – thus, 1120 SP / 56 TMU. The forum member upon agrees with the same specifications and suggests HD 5700 may release as soon as 12th October – 10 days ahead of schedule.
The HD 5750 itself is much shorter than HD 5800 cards. In fact, it appears to be as short as similar entry level products such as a 9500 GT or a HD 4670. It does take up two slots, however, although unfortunately, the cooler does not blow the hot air straight out of the case. We have the same 4 display outputs as the HD 5800 series. The die size is expected to be around 180 mm2 for Juniper, which is rather small for a performance product, which means it is cheap to produce and runs rather cool – 70C in Furmark is an impressive result. The HD 5750 is powered by a single 6 pin PCI-e connector, suggesting a TDP of around 100W. Judging by these details – surely AIB partners would step in to create single slot solutions, or perhaps even low-profile ones.
The HD 5750 runs at 700 / 1150 (core/memory) with a memory bandwidth of 74 GB/s. Once again, concerns of a memory bandwidth bottleneck are sure to be discussed. That said, the HD 5750 may have shaders disabled, maybe at 960 SP, which means the situation is no worse than the HD 4850. Surely, we can expect the HD 5770 to ship with higher memory clocks, though there seems to be no mention of a 192-bit interface any longer.
Coming to performance, we have two 3DMark scores for what will be an affordable $149 card. The 5750 outperforms the GTS 250 but barely sneaks by the HD 4770. We expected more, for sure, as these scores will not hold up well against the 5750’s real competitors – the GTX 260 and HD 4870. However, this is just one benchmark, and surely, the tests were conducted on immature drivers.
The HD 5770 is expected to release at $199, which is a full 33% more than the HD 5750. At that price, it will take on the HD 4890 and GTX 275.
