Intel Core 2 Duo E7300 VS. AMD Athlon X2 7750

Kuma, 2.7GHz, 200MHz FSB, 13.5x multiplier, each core 64K L1 instruction Cache and 64K L1 data Cache, 2×512KB L2 cache, 2MB L3 cache and it supports SSE, SSE2, SSE3, SSE4A and X86-64. In AthlonX2 7750 black edition reviewed we contrasted its performances with Athlon X2 5400＋ black edition and it really improved a lot.

Currently, Core 2 Duo E7300 is about 110$ while Athlon X2 7750 is about 70$.AMD 790GX is about 85$ while NVIDIA MCP7A is about 100$.

AMD Athlon X2 7750 Review

AMD is also launching a new CPU series codenamed Kuma. This is a Stars core with a 2MB L3 cache and the Hypertransport bus runs at 1.8Ghz instead of 1GHz of most dual cores. We don't have a lot more technical information on the processor at this time but we'll update this review when we get more. For now here's what you probably care about: benchmarks and overclocking.


Here's our test system.

Mother Board Gigabyte 790GX
Memory Corsair XMS 4GB
Hard Drive Western Digital SE 16 750GB
Case Tsunami Thermaltake
Display Samsung SyncMaster 30"

Windows Vista x86 SP1 was our test system with ATI Catalyst 8.12 drivers. The only vanilla X2 we had on hand was the X2 5000+ which runs at 2.6GHz so we down clocked our 7750 to 2.6GHz from 2.7GHz. Usually this is fairly accurate representation of what a processor with that stock clock would perform at though occasionally it is faster.

With more performance comes more power taking another 20W to run at idle and 25W at load under Valve Map creation benchmark under load. Cool 'n Quiet was disabled with testing.

Kuma seems like a good bump up from the previous Athlon 64 X2 dual cores though the L3 cache and higher Hypertransport bus do increase overall power consumption. We don't have retail pricing at this time but we will update the review when we see the processor at e-tailers. We wish we had time to compare this to an Intel dual core processors but unfortunately we're a bit strapped for time. This should definitely help keep AMD more competitive in the dual core arena and is a nice part to tide things over until Phenom II.

Kuma to become Athlon X2 7550/7750

AMD is going to pick up the Kuma core. Back in September we have reviewed an ES version Kuma. At that time we thought the Kuma would become Athlon 6500+. But no words in AMD’s September roadmap about Kuma, we think AMD have dropped it.

But when we saw AMD’s October roadmap, Kuma appears and branded as“Athlon X2 7550/7750”.

According to the roadmap, Athlon X2 7550 will be a 2.5GHz Kuma, except the clock all other spec is the same with our ES version. Athlon X2 7750 runs at 2.7GHz. For cache,TDP and other information, you can read the chart we compiled.

So there is no more Athlon 6500+, AMD wants Kuma to be 7 series dual core. Both of the chips will come out in 09Q1. The company positioned Kuma to encounter intel E7400 and E7300. Do you think Kuma can beat them? Tell us how you think about it!

AMD denies Kuma cancellation rumors

Earlier this week the word around Rumorville was that AMD decided to abandon its plans of releasing dual-core K10 (codenamed Kuma) processors. As just stated by AMD spokesman Jake Whitman though, this is just not true as the company is still "on track to launch a dual-core -codenamed Kuma - part in the second half of '08."

Set to utilize the Athlon brand, the Kuma CPUs will be built on 65nm, feature HyperTransport 3.0 and come in an AM2+ package.
