Multi-channel Multi-rate 1.6T Ethernet Package (E-pak 1p6T IP Core)
The E-pak SOC Core from Precise-ITC is a multi-rate Ethernet aggregator that supports tributaries from 800GE, to 1GE. E-pak 1.6T is our 5th generation of E-pak solution utilizing the 112G/s serdes and 56G/s serdes. The SOC consists of Epak 1p6T MC PCS and Epak 1p6T MC MAC Core.
The supported ethernet protocols are 800GE, 400GE, 200GE, 100GE, 50GE, 40GE, 25GE, 10GE and 1GE. It supports any legal combination of ethernet rate up to 800G. This Core supports up to a maximum of 8 ethernet channel and works most effective and efficient with latest 112G/s serdes. With Core clock frequency of 670MHz to 1.6GHz at 7nm or 5nm, this Core delivers smallest footprint among similar solution in the Ethernet SOC market.
800GE Support
The Core supports 800GE which uses a full 800GE MAC and a pair of “bonded” 2 x 400GE PCS. The 800GE takes advantage of 112G/s serdes and uses virtual logical lanes in a “bonded” 2 x 400GE PCS. This improves power efficiency in 800G operation. The 800GE is compliant to the Ethernet Technology Consortium Standard.
Overview
The north-bound interface from the multi-channel MAC provides a configurable system interface. The Multi-channel MAC manages the mapping between individual MACs and the assigned I/O or I/O group.
The southbound interface is mapped (at the PMA layer) to the on-chip SERDES. The core is responsible for channel alignment and FEC (where applicable).
Benefits

How do the Intel Core Solo, Core Duo, Core 2, and new quad-core CPUs compare? That’s the question Primate Labs addresses in their latest Geekbench Comparison.
Geekbench 2 is designed to measure CPU and memory performance, not graphics, an area where the Mac mini, MacBook, and entry-level iMac fall behind the rest of the pack with their integrated Intel GMA 950 graphics.
Primate Labs’ conclusion:
“There’s not a huge change in performance across most of Apple’s Intel-based Mac lineup (the high-end MacBook Pro Core 2 Duo is only 30% faster than the low-end MacBook Core Duo, for example). The only big changes occur at the low end with the (discontinued) single-core Mac mini, or at the high end with the quad-core Mac Pro.”
Let’s see if the numbers really bear that out.
Seasonality Core 2 6 X 8 Runner Rug Farmhouse
How Low Can You Go?
The baseline score of 1000 is based on performance of a 1.6 GHz single processor Power Mac G5. Even the least powerful Intel-based Mac ever released, the Core Solo version of the Early 2006 Mac mini, outperformed it with a score of 1472 (just under 1000 points per GHz).
This is the only Mac ever released with a Core Solo CPU, and it really does make a difference. One step higher, from the 1.5 GHz Solo to a 1.66 GHz Duo, boosts the benchmark score by 50%. The 1.66 GHz Mac mini scores 2136, and the newer 1.83 GHz mini scores 2312, an 8.3% improvement (just a bit less than the 10% difference in clock speed).
There’s an 11% difference in clock speed between 1.5 GHz and 1.66 GHz, and we anticipate a 1.5 GHz Core Duo would benchmark at roughly 1960. That means the second core on the original Core Duo CPU provides about one-third more power.
By way of comparison, the G4 Mac mini offered a lot less horsepower. The fastest model runs at 1.5 GHz and achieves a Geekbench score of 862 (or just 575 per GHz). The Core Solo mini beats that by over 50%.
Other Core Duo Results
- 1.83 GHz Mac mini: 2312
- 1.83 GHz MacBook Pro: 2333
- 1.83 GHz MacBook: 2363
- 1.83 GHz iMac: 2373
- 2.0 GHz MacBook: 2475
- 2.0 GHz MacBook Pro: 2495
- 2.0 GHz iMac: 2556
- 2.16 GHz MacBook Pro: 2711
Benchmark results are very close across the board for the 1.83 GHz Core Duo, and the range of 2.0 GHz results is only slightly broader. The CPU benches 1295 per GHz in the 1.83 GHz iMac, 1278 in the 2.0 GHz iMac, and 1251 in the 2.16 GHz MacBook Pro, showing that performance is being constrained by the memory bus, not the CPU.
Core 2 Improvements
Comparing the 2.0 GHz MacBook, we have a Geekbench score of 2475 with the Core Duo and 2600 with the Core 2 Duo, a 5% improvement. Moving to the 2.16 GHz MacBook Pro, the Core Duo model scores 2711 while the Core 2 unit reaches 2825 – an improvement of 4.2%.
The 2.0 GHz iMac goes from 2556 with Core Duo to 2654 with Core 2 Duo, a boost of just 3.8%. There is no Core 2 Mac mini, no was there a Core Duo version of the Mac Pro.
Four Cores
The Mac Pro was initially available in 2.0, 2.66, and 3.0 GHz versions, to which Apple added a 3.0 GHz dual quad-core version last week. The best comparison to other Macs is at 2.0 GHz:
- MacBook: 2600 (1300 per GHz)
- iMac: 2654 (1327 per GHz)
- Mac Pro: 3926 (1963 per GHz)
With a pair of dual-core Xeon CPUs, the Mac Pro scores 48% higher than the iMac with a single Core 2 Duo CPU using Geekbench 2. Here’s how the Mac Pro scales at different clock speeds:
- 2.0 GHz, 3926 (1963 per GHz)
- 2.66 GHz, 5034 (1888 per GHz)
- 3.0 GHz, 5611 (1870 per GHz)
These numbers show that the Mac Pro is well optimized for fast CPUs, as there’s only a 1% difference in the Geekbench score per GHz rating of the faster models.
The highest Geekbench scores have been achieved by our friends at Bare Feats on the new 8-core (two quad-core CPUs) Mac Pro. With a score of 8735, that comes out to 2912 per GHz – a 56% higher score than the Core 2 Duo at the same speed.
And if you look back that the 1.5 GHz Core Solo Mac mini, that’s about 3x the efficiency and 6x the overall score. Pretty good for a computer with a lot more expandability, far better graphics, and only 5x the price.
What About the Power Mac?
How does the Power Mac G5 fare under Geekbench? There are several results for the Late 2005 Power Mac G5, and the highest scores are in the 3300 to 3400 range. Assuming that’s the 2.5 GHz Quad gives a rating of 1356 per GHz.
If you’re wondering what Apple gained by going Intel, there you have it. A single Intel Core 2 Duo offers about the same performance per GHz as a pair of dual-core G5s.
That’s two dual-core PowerPC 970MP CPUs with about the same score as a single dual-core Core 2 Duo CPU in an iMac. (For comparison, the 1.67 GHz PowerBook G4 tops out at a score of 937 – or just 562 per GHz – and the 1.42 GHz dual CPU Power Mac G4 only achieves a 1248 for 878 per GHz. The “underwhelming” 1.5 GHz Core Solo Mac mini beats that!)
What Does It All Mean?
Every benchmark is different. Geekbench looks primarily at CPU and RAM performance. Other benchmarks are more interested in drive speed, overall graphics, 3D gaming, or broader real world performance. They’re all carefully measured numbers that really only tell you how well a computer does at a particular task.
Still, they will show how one computer fares relative to another. Based on the Geekbench results, we see that doubling the number of cores can improve scores by 33% to 56%, which is very impressive. (But not as impressive as in the early days of dual G4 Power Macs and Mac-specific benchmarks that tended to show a 50-70% improvement. Then again, those were different benchmark programs and a different CPU architecture.)
Sure, there are benchmarks that will show a nearly 100% improvement, but that tends to be over a limited range of processes. A 50% average gain in processing power is nothing to sneeze at, and it’s an especially good value when there’s a minimal premium for the extra power. The 8-core Mac Pro is a great example of that, as it offers about 56% more power than the 4-core Mac Pro while selling at a 21% higher price.
Ad free audio capture 2 2 07. The transition from Core to Core 2 doesn’t look as impressive with Geekbench as it does with some other benchmarks. Our general rule of thumb is that Core 2 is roughly 10% more powerful than “Core 1” – the big gains are in reduced energy consumption, longer battery life, and less heat.
We’re grateful to Primate Labs for producing Geekbench and publishing these results. They show us that Apple and Intel are moving in the right direction, especially as regards multiple cores and the future of computing.
