The German website notebookjournal.de just released a review of HD5650 and Core i7-720QM equipped notebook which shows the performance of the new ATI mobile graphics card codenamed Madison, which we expect to see in most Acer models coming in January and may be many other in the next few months. The review lacks much data about the graphics card and it’s prone to speculations, but it shows that HD5650 will run at 600 MHz core and 800 MHz memory (600 MHz DDR) and it is equipped with 1 GB of GDDR3 memory.
You can check the charts at notebookjournal.de review of DevilTech Fire DTX notebook here. Mobility Radeon HD5650 performs well against it’s main competitors, namely the NVIDIA GeForce GTS 250M, and it runs much cooler due to its 40 nm manufacturing process. It is unknown how much stream processors it has, but judging from its obvious advantage over Mobility Radeon HD4670, which works at 680 MHz core and hase the same 128-bit memory buss and GDDR3 memory, it should have 400 (80×5) stream processors, similar to desktop 5670 graphics card.
The Madison Pro version is supposed to deliver a bit more power and it might be the HD5670 – running at higher clocks or even featuring GDDR5 memory, but that remains unclear until ATI decides to share some information. It is obvious that the bottleneck of HD56xx series will be their memory interface/speed, same way it was with HD4670. NVIDIA would struggle to offer competative solution at this moment, as both GTS 160M (65 nm, hot) and the GTS 250M have worse consumption, even though they deliver more raw power. DirectX 11 has insignificant role in notebook market as there is no related performance gain, which is essential for notebooks, yet it also manages to give ATI’s new mobile cards an edge.
The results notebookjournal.de leaked are rather dissapointing, as the performance gain over HD4670 is marginal and has nothing to do with theose big jumps in peerformance we are used to see in desktop cards. Yet the card is cooler, DirecX 11 compatible and there is room for perfection in the upcomming HD5670.
3 out of 10 because its a bit closer to HD4670 than we expected, yet it has nice features. Result can be changed once we get our hands on HD56x0-based notebook.
Higher Twisted Rating is worse!
