With modern games at older resolutions like p, we do see a sizable gain when the K is overclocked. However, all those gains are muted at a higher resolutions setting, such as p. At an enthusiast 4K setting, the results across the board are almost equal.
As resolutions are getting higher, even with modern physics and instructions and APIs, the bulk of the workload is still on the GPU, and even the Core iK is powerful enough for it. Sandy Bridge marked a turning point in performance on x86 which took AMD another eight years to catch up with its Ryzen series. As tests show, its great popularity was no coincidence, with people still happily using Sandy Bridge processors even today.
But let's do some math. So if we start back at Conroe and work our way to present day Ivy Bridge, that's 5 new generations of processors. Once you take into account faster clock speeds, number of cores, cache sizes, integrated memory controllers, etc. I digress. The point being, is I would like to see some more benchies Tom's! Prove me wrong! Lot of great info here, but missing Core i3 info leaves a big hole in the data point.
During our benchmarks tests we also recorded the power consumption of our Schenker P test system. Nevertheless, it allows to illustrate the range of the new Sandy-Bridge family.
When Idle , i. It's quite different under load. Furthermore, we observed the power consumption of our test system during the wPrime benchmark , version 1.
This test allows to predefine the number of available threads. According to the figure we can conclude the following: The more threads are used the bigger the difference between QM and XM CPU in terms of energy demand. The curve of the power consumption for the QM CPU is clearly flatter and does not increase much from about 5 threads on.
On the contrary, the power consumption of the Extreme CPU increases perceptibly up to eight threads, even if the curve gets flatter in the range between threads too. Our tests prove what was to be expected according to some information leaked out in advance: Intel's new quad core Sandy Bridge CPU line up brings a huge performance gain compared to the existing Clarksfield CPUs.
We saw repeatedly that the iQM processor , i. This impressively points out the success of the new CPU architecture, which largely exceeds the impact of simply higher clock rates. So, you'll get more power by buying an iQM for US-Dollar recommended price so far , which is about the same an iQM cost so far, than an iXM processor delivered, which cost steep dollar. At the time of writing, the five quad core processors and five dual-core models are introduced.
The later will be scrutinized in detail in a coming review. However, these models cost about the same or slightly more than their standard dual core counterparts. As usual, detailed information about the new Sandy Bridge processors is available on our continuously updated Mobile Processors - Benchmark List and on the specific pages for each CPU linked there.
Many thanks to Schenker-Notebook who kindly provided us with the test system. The laptop can be configured and also bought here soon. Intel once again refreshed its CPU architecture and renewed the whole processor lineup. Read on to learn about the new features and the performance of the new processors. Intel: Tick-Tock Model.
