Intel Iris Pro 5200 Graphics Review: Core i7-4950HQ Testedby Anand Lal Shimpi on June 1, 2013 10:01 AM EST
Intel's launch lineup with Haswell is pretty spartan, but we do have enough information to get a general idea of what Crystalwell will cost as an addition.
|Peak Theoretical GPU Performance|
|CPU Cores/Threads||CPU Clock (Base/4C/2C/1C Turbo)||Graphics||GPU Clock (Base/Max Turbo)||TDP||Price|
|Intel Core i7-4950HQ||4/8||2.4/3.4/3.5/3.6GHz||Intel Iris Pro 5200||200/1300MHz||47W||$657|
|Intel Core i7-4850HQ||4/8||2.3/3.3/3.4/3.5GHz||Intel Iris Pro 5200||200/1300MHz||47W||$468|
|Intel Core i7-4800MQ||4/8||2.7/3.5/3.6/3.7GHz||Intel HD 4600||400/1300MHz||47W||$378|
The i7-4950HQ and i7-4850HQ are the only two Iris Pro 5200 parts launching today. A slower 2GHz i7-4750HQ will follow sometime in Q3. CPU clocks are a bit lower when you go to GT3, likely to preserve yield. Compared to the i7-4800MQ the 4850HQ carries a $90 premium. That $90 gives you twice the number of graphics EUs as well as the 128MB of eDRAM. Both adders are likely similar in terms of die area, putting the value of both at $45 a piece. Now you are giving up a bit on the CPU frequency side, so the actual cost could be closer to $50 or so for each. Either way, Iris Pro 5200 doesn't come cheap - especially compared to Intel's HD 4600.
From talking to OEMs, NVIDIA seems to offer better performance at equivalent pricing with their GT 740M/750M solutions, which is why many PC OEMs have decided to go that route for their Haswell launch platforms. What Intel hopes however is that the power savings by going to a single 47W part will win over OEMs in the long run, after all, we are talking about notebooks here.
